Faisal Bashir, ... Dan Schonfeld, in The Electrical Engineering Handbook, 2005. For more detailed information on those topics, see publications in the related fields (Hanjalic et al., 2006; Sebe et al., 2007; Divakaran, 2009; Ohm, 2016). Such adaptations may be at the system level (e.g., adjustment of network parameters to enable more effective information collection), or at the application level to achieve new functionalities or to optimize overall application goals (e.g., automated control of devices based on user behavior to conserve energy). The goal of this chapter is to identify fundamental challenges in building large-scale sentient spaces. Multimedia data refers to pictures, videos, and images scanned into a computer. It will also discuss the role of formal methods and reasoning in the realization of such a middleware framework. Designers can use it to convey specific information, reinforce an idea or make a website more accessible. Kandel et al. Such a programming environment will empower the application writers to express their higher-level application goals which are then translated into lower-level sensor-specific programs by the system. L'assistant / assistante son assure la préparation des séances d’enregistrement sonore. Taekyong Lee, ... Gultekin Özsoyoglu, in Readings in Multimedia Computing and Networking, 2002. These are typically the elements or the building blocks of ore generalized multimedia environments, platforms, or integrating tools. Once a concept detector is established, the detector can be used to automatically annotate the rest of the data (Rui and Qi, 2007). Along with the increasing demand for the development of modern digital imaging devices, there are increasing requirements for efficient image denoising algorithms with greater image quality and their real-time applications. Multimedia processing has been researched extensively in the signal processing community, and thousands of papers have been published. A multimedia presentation is a synchronized and, possibly, interactive delivery of, Research Methods in Human Computer Interaction (Second Edition), Hanjalic et al., 2006; Sebe et al., 2007; Divakaran, 2009; Ohm, 2016, Pervasive Sensing and Monitoring for Situational Awareness, Handbook on Securing Cyber-Physical Critical Infrastructure, Lossless Information Hiding in JPEG- and JPEG2000-Compressed Images, An efficient pure color image denoising using quantum parallel bidirectional self-organizing neural network architecture, Quantum Inspired Computational Intelligence, Journal of Network and Computer Applications, AEU - International Journal of Electronics and Communications.

Recently, wavelet [4, 5], curvelet [6], and ridgelet [7] transformation-based techniques have become popular for color image denoising. Multimedia formats, however, are much more complex than most other file formats because of the wide variety of data they must store. At last, a summary is given. Without the support of automated tools, the researcher would have to manually go through hours of audio or video recordings to identify and code the instances of specific interest. Java Media Frameworks. Although existing efforts provide effective data processing capabilities over continuous streams of data, it exhibits significant limitations, in our view, to serve as a platform for building sentient spaces. Data. This section describes working with waveform-audio devices, and includes information on how to open, close and query them for their capabilities. 4. Query 6 and Query 7 can be expressed and answered by the current prototype, although better techniques for answering Query 7 are being investigated. Finally, even if all relevant object characteristics are annotated, difficulty may still arise due to the use of different indexing languages or vocabularies by different users. The files size makes it time-consuming to move them from place to place over school networks or to distribute over the Internet. Audio consists of a sequence of digitised sounds. The completely automated approach is less labor intensive. Each child record in the tree will contain only one parent. To query multimedia presentation graphs, this paper discusses GVISUAL, which is an icon-based object-oriented graphical query language. Ghose, in Quantum Inspired Computational Intelligence, 2017. Thus the lossless information hiding schemes for JPEG images are considered by many scholars. Multimedia data, such as text, audio, images and video, are rapidly evolving as main avenues for the creation, exchange, and storage of information in the modern era. Techniques to support robust/trusted situational awareness that will handle small physical perturbations to sensors (e.g., due to wind, tampering), large system failures, and network losses must be designed. Such search algorithms can become unusable if the number of documents to be searched becomes too large. Then, we introduce the lossless information hiding schemes for JPEG-compressed images and JPEG2000-compressed images. Color image denoising approaches in the frequency domain and primitive smoothing filters have also contributed significantly in this field of research. In this section, our study of multimedia data mining focuses on image data mining. It is the type of database that stores data in the form of parent-children relationship nodes. Before we discuss challenges and describe emerging technological advances to address them, we briefly discuss existing work on data streaming systems and sensor networks. Recently, Yahoo's S4 system has explored an actor-based framework to scale stream processing dynamically by exploiting cloud resources [18]. various types of multimedia data. Paths of a multimedia presentation graph are specified by using computational tree logic [21] (extended with different semantics for path quantification [34]), and temporal operators of propositional linear temporal logic [21], [55] (extended with node and path variables). that enable efficient storage and communication. It is not unusual for an organization to have a requirement that these documents be kept for long periods of time. Mu… Section 10 concludes with the scope of future research. Devices and Data Types. Multimedia Data Types. Most likely, the requirement would involve using digital cameras, with the resulting computer files typed to the representation format. Multimedia data is a combination of video, audio, text, graphics, still images, and animation data. Finally, the one-sided Kolmogorov-Smirnov (KS) test is performed to show the statistical superiority of the proposed method. (See the "MIDI Standard" section later in this chapter.) In order for a multimedia database to work, the database needs to manage several types of data. A vivid explanation of the network dynamics of the functioning and the operation related to adjustments of weighted interconnections of the network of the QPBDSONN architecture is included in this section. Dragicevic et al. Commonly-used file extensions for MPEG multimedia video formats include .mpeg, .mpg, and .mp4. Wilhelm et al. These include techniques for improved ad hoc programming of sensor networks via dynamic code upload to each node [19] or providing a database-like view of the sensor network and pushing the execution of the relational operators into the WSN nodes [20]. From a user’s perspective, a device is considered more modern if it can load multimedia components and has multimedia capability. VISUAL is briefly reviewed in Section 3. Does the lesion overlap any of the activated areas from the functional MRI study? JPEG2000 is a new international standard for still image compression, which is based on wavelet transform and embedded block coding with optimized truncation algorithm [1,2]. The current technology of text-based indexing and retrieval implemented for relational databases does not provide practical solutions for this problem of managing huge multimedia repositories. In Section 6, we briefly discuss the expressive power and user friendliness of GVISUAL. Types of Multimedia. Section 9 concludes. Owing to the inherent nonlinearity offered by the median filter, it is efficient in preserving the edges of the object from a noisy perspective. DIFFERENTS TYPES DE DOCUMENTS MULTIMEDIAS ET LEURS CARACTERISTIQUES Un document multimédia (diaporama, vidéo, pages web, …) est un fichier informatique qui intègre un ensemble d'informations et de ressources numériques (textes, images 2D et 3D, tableaux, graphiques, sons, animations, vidéos). In common usage, people refer a data set as multimedia only when time-dependent data such as audio and video … 12 Types of Interactive Media posted by John Spacey, September 06, 2017. The most common form of multimedia in this classification is text. As recently as the 1990s, these major drawbacks of searching visual media based on textual annotations were recognized as unavoidable, and this prompted a surging increase in interest in content-based solutions (Goodrum, 2000). Audio data contained in MPEG files are usually compressed within the MPEG Audio Layer III format, one of the most popular multimedia audio formats available. Simply, a multimedia presentation graph specifies the playout order of various types of streams making up the multimedia presentation, i.e., it is a visual specification of a presentation plan. In this paper, we illustrate our contributions using only the video multimedia data type. Following are the various categories of Multimedia software 1. In the early days of computing, data consisted primarily of text and numbers, but in modern-day computing, there are lots of different multimedia data types, such as audio, images, graphics and video. None of the previous approaches provides the level of abstraction desired for programming sentient spaces; in many cases, they require the application to specify exactly how to answer a query. Other topics in multimedia mining include classification and prediction analysis, mining associations, and video and audio data mining (Section 13.2.3). Audio , video and animation). … The applications to facilitate manual coding have shown promising results but improvements are also needed to improve the usability and reliability of those systems. New programming abstractions required for programming sentient space applications that hide application programmers from having to deal with heterogeneity of sensors, low-level details of the specific sensor devices, or to write defensive code to overcome errors and failures. There are number of data types that can be characterized as multimedia data types. A program that uses the data in a file must be able to recognize and possibly access data within the file. ), the thesis of this chapter is that much of the desired functionalities should be incorporated in an adaptive middleware environment. A multimedia presentation is a synchronized and, possibly, interactive delivery of multimedia data to users. Section 6 sheds light on the parallel architecture and its principle of its operation in a parallel bidirectional self-organizing neural network (PBDSONN) [19, 20]. The rest of the paper is organized as follows: The data model for multimedia presentation graphs is given in Section 2. Over the past decade, various stream-processing engines (SPEs) such as TelegraphCQ [1], STREAMS [2], S3 [3], Cayuga [4], Aurora [5], Borealis [6], and MedSMan [7] have been proposed in the literature and many related commercial products have been developed (e.g., S4 by Yahoo). An archiving solution may consider pre-searching objects as they are placed in the archive and building external indexes of common characteristics. In content-based retrieval, manual annotation of visual media is avoided, and indexing and retrieval are instead performed on the basis of media content itself. The multimedia computer system stores, represents, processes, manipulates, and makes available to users. Video and film based content such as television, movies, promotional videos, commercials and video-sharing websites. Multimedia Development Environments. If interactivity is added, this is known as hypermedia. image and graphic object ). Classifying is a second way of thinking through multimedia and it is the one that involves surveying the variety of the phenomena. These languages extend SQL with window operators, relation-to-stream operators, syntax to specify the sampling period and the lifetime of the sensor network, and even syntax to generate output streams based on the query result. We will finally discuss our ongoing efforts in developing such a middleware framework – SATWARE built on top of the Responsphere pervasive instrumented space at UC Irvine. The ChronoViz tool supports playback and review of multiple, synchronized streams of multimedia data (Fouse et al., 2011). According to a press release by Google Inc. in December 2001, the search engine offers access to over 3 billion Web documents and its Image search comprises more that 330 million images. The term "video", if not used exclusively to describe motion photography, is ambiguous in multimedia terminology. In particular, robust techniques are needed to develop semantically rich models to represent data, computationally efficient methods to compress, index, retrieve, and browse the information; and semantic visual interfaces integrating the above components into viable multimedia systems. Techniques for automatic annotation still need substantial advancements in order to achieve reliable coding. Specialized presentation programs are needed to display the archived documents. Multimedia data refers to data that consist of various media types like text, audio, video, and animation. Media Conversion Tools- These tools are used for encoding / decoding multimedia contexts and for converting one file format to another. We use cookies to help provide and enhance our service and tailor content and ads. First, it is often difficult to describe with human languages the content of a multimedia object (e.g., an image having complicated texture patterns). Multimedia information also presents substantial challenges for data analysis. The principal objective of the research reported in this chapter is given in Section 3. For this same reason, multimedia data processing technologies are not covered extensively in this book; rather, only a few papers have been selected to provide some background for immersive audio in Chapter 1 and for image and video compression and watermarking in Chapter 2. We will discuss technological advances in event-processing architectures that can help develop a wide range of situational awareness applications. It has huge storage capacity. This chapter will discuss design principles in the creation of the sensing and monitoring middleware for pervasive spaces that can address the multifaceted challenges of scalability, robustness, and flexibility. Dynamic media (time dependent, moving, interactive, e.g. Path formulas not only can specify paths constructed by the nodes of a presentation graph, but also specify content changes among frames of streams and hierarchical relationships between a stream and its contents. Considering the huge amount of information that needs to be annotated, the manual approach is extremely labor intensive. Computer systems work with different types of digital data. Ce spécialiste de la data à au minimum un niveau bac + 5. Multimedia can be either: - Text & Hypertext. Gives information about different types of data to be dealt in processing multimedia information. A recently developed adaptive wavelet thresholding accomplished with a median filter [18] has been extensively applied on two-dimensional digital images for image denoising. This chapter is organized as follows: Section 2 provides a detailed literature survey focusing on color image denoising and extraction of a pure colored object. 16/17 Sharad Mehrotra, ... Carolyn Talcott, in Handbook on Securing Cyber-Physical Critical Infrastructure, 2012. Database management systems (ITE1003) Uploaded by. Multimedia Editing Tools- These tools are used for creating and editing digital multimedia data. It also describes how to keep track of the devices in a system by using device handles and device identifiers. Also to have realistic video playback, the transmission, compression, and decompression of digitalized require continuous transfer rate. Third, since users may have different interests in the same multimedia object, it is difficult to describe it with a complete set of keywords. It is also a general move in any discussion of multimedia to give examples of these types of multimedia especially to make the point that these types are no longer academic experiments which is inaccessible to the everyday consumer. To model multimedia data as objects using XML, we take two main features of the standard object-oriented data model [3]: object identity and object nesting. The specific algorithms or techniques of multimedia content analysis are still seeing dramatic advances. By continuing you agree to the use of cookies. Service-oriented middlewares (SOM) for pervasive spaces such as Gaia [10], Oxygen [11], PICO [12], Scooby [13], and Aura take an approach similar to Aurora and Borealis where applications are described as graphs of services. (2008) proposed the PhotoSpread system, which allows users to organize and analyze photos and images via an easy-to-use spreadsheet with direct manipulation functions. The first type is the media data. Saravanakumar Kandasamy. - Animations & Video. Applications that support content visualization for easy data sharing and analysis have also been developed (Cristani et al., 2008). John David N. Dionisio, Alfonso F. Cárdenas, in Readings in Multimedia Computing and Networking, 2002. Recently, commercial multimedia authoring tools have added database access or a database front end to let users access media files and clip libraries. Wavelet thresholding has proved to be efficient in reducing blurring effects by means of a discrete wavelet transform, a discrete Fourier transform, or a discrete cosine transform [17], to name a few methods. The queries below show predicates that cannot be answered solely from alphanumeric information. Although these approaches stand in good stead in some cases, they seldom pay any heed to the human visual perception system, resulting in their being undesirable in cluttered or noisy environments. Commonly used forms of data are numbers, alphanumeric, text, images, audio, and video. In addition, it can also be affected by the coder's subjective interpretation. For querying multimedia presentation graphs (or graphs in general), new constructs of GVISUAL that are graphical representations of temporal operators allow users to express relationships between nodes, edges, and paths along presentation graphs. Section 7 summarizes the GVISUAL implementation effort and the ongoing work on query processing in GVISUAL. 05/31/2018; 7 minutes to read; In this article. Color image denoising involves the process of extraction of a pure color object from a noisy environment. They first automatically partitioned the video footage into small “sessions,” then manually coded the information in which they were interested (the duration of interaction, the number of active users, and the number of passive bystanders). Multimedia presentations are used extensively in many applications such as computer-aided training, computer-aided learning, world wide web sites, product demonstrations, document presentations, … To segment the nonredundant useful foreground region from the larger background area of color images, plentiful linear and nonlinear classical smoothing filters [1] in both the spatial and the temporal domain have been developed over the decades. Another application domain related to multimedia content analysis is the online search of media content. So far, annotation can be accomplished through three approaches: manual annotation, partially automated annotation, and completely automated annotation. Deeply instrumented physical spaces generate sensor data that is used to create digital representations of the physical world, which can then be used to implement new functionalities or improve existing ones, and to adapt the configuration of the system itself, we refer to such cyber-physical spaces as sentient spaces. Alta Vista Inc. has been serving around 25 million search queries per day in more than 25 languages, with its multimedia search featuring over 45 million images, videos, and audio clips. These data types are broadly categorized into three classes:: Static media (time independent, constant, non interactive e.g. GVISUAL is a graphical icon-based query language for the graph data model and extends VISUAL [11]. Query 8 can be expressed but not answered by the current prototype. 6.0 Types of File Format. Compression shrinks files, making them smaller and Significant Features of Multimedia Computer System. Each device in the pervasive/ubiquitous space advertises its capabilities as services. Typical real-time applications include defense, content-based image retrieval, surveillance, and biomedical applications, to name a few. Video : One on the most space consuming multimedia data type is digitalized video. Multimedia is a technology which stores data as text, photo, animation, music, video, etc. Such a framework will also enable effective reasoning about observations and actions to bring about effective adaptations of both the system behavior and the pervasive application. Depending upon its resolution and size a single frame can consume upto 1 MB. Multimedia data can be used in MQuery not only as query results but also as participants in the actual predicates. Advances in multimedia technologies make it possible now for us to provide instant information access to any type of information one desires -- text, data, still image, motion picture, and sound. Audio. Chapters 4 and 5Chapter 4Chapter 5 focused on lossless information hiding techniques for vector quantization–and block truncation coding–compressed images, respectively; this chapter deals with lossless information hiding techniques for JPEG- and JPEG2000-compressed images in this chapter. The types of file format in multimedia have many ways are image, music, video and more. Data get stored in the form of records that are connected via links. Situational awareness, in a broad sense, refers to a continuum of knowledge that captures the current state of the physical environments being observed to future projected states of these observed environments. Sources in form of text, video, image, maps, or sound. This chapter reviews the state-of-the-art research in the area of multimedia systems. The division of multimedia into the first five types is common in web design, where the designer uses a combination of these types to deliver functional content to an end user. The inherent drawback with these linear filtering approaches is blurring effects and therefore poor quality of images extracted from noisy versions. Human coders manually annotate a subset of the multimedia data. D. Konar, ... M.K. Such awareness is created through processing of data from the sensed environment. However, there are only a few related studies on information hiding for JPEG2000 images. To denoise the images affected by uniform and Gaussian noise, linear smoothing filters such as the nonlocal mean filter, shape-adaptive transform [10], bilateral filtering [11, 12], nonlocal mean-based methods [13, 14], and nonlocal collaborative filtering [15, 16] can be used. You need to identify the key instances that you want to describe or annotate. There are three different types of data used, when it comes to the productions of Multimedia presentation. Multimedia technology typically refers to any type of technology that can be used in the creation or display of multimedia content, which usually consists of combinations of images and audio in a single application. In addition to the automatic annotation applications, a number of other tools have been developed to facilitate the process of multimedia content analysis. Although the issue of data privacy has received significant research attention in the context of Internet-based applications (wherein websites store individual-centric data) and in collecting and disseminating electronic medical records, pervasive systems that continuously capture and process information such as location, activity, and interactions using sensing technologies raises additional challenges by introducing additional inference channels.
