This book was released on 2012-12-06 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recursive Block Coding, a new image data compression technique that has its roots in noncausal models for 1d and 2d signals, is the subject of this book. The underlying theory provides a multitude of compression algorithms that encompass two course coding, quad tree coding, hybrid coding and so on. Since the noncausal models provide a fundamentally different image representation, they lead to new approaches to many existing algorithms, including useful approaches for asymmetric, progressive, and adaptive coding techniques. On the theoretical front, the basic result shows that a random field (an ensemble of images) can be coded block by block such that the interblock redundancy can be completely removed while the individual blocks are transform coded. On the practical side, the artifact of tiling, a block boundary effect, present in conventional block by block transform coding techniques has been greatly suppressed. This book contains not only a theoretical discussion of the algorithms but also exhaustive simulation and suggested methodologies for ensemble design techniques. Each of the resulting algorithms has been applied to twelve images over a wide range of image data rates and the results are reported using subjective descriptions, photographs, mathematical MSE values, and h-plots, a recently proposed graphical representation showing a high level of agreement with image quality as judged subjectively.

The special session papers deal with content analysis for human-centered multimedia applications; large scale rich media data management; multimedia understanding for consumer electronics; image object recognition and compression; and interactive image and video search.

Download or read book Perceptual Image Coding with Discrete Cosine Transform written by Ee-Leng Tan and published by Springer. This book was released on 2015-05-13 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book first introduces classic as well as recent computational models for just-noticeable-difference (JND) applications. Since the discrete cosine transform (DCT) is applied in many image and video standards (JPEG, MPEG-1/2/4, H.261/3), the book also includes a comprehensive survey of computational models for JND that are based on DCT. The visual factors used in these computational models are reviewed in detail. Further, an extensive comparative analysis of these models using quantitative and qualitative performance criteria is presented, which compares the noise shaping performance of these models with subjective evaluation and the accuracy between the estimated JND thresholds and subjective evaluation. There are many surveys available on computational models for JND; however, these surveys seldom compare the performance of computational models that are based on DCT. The authors’ survey of the computational models and their in-depth review of the visual factors used in them will help readers understand perceptual image coding based on DCT. The book also provides a comparative analysis of several perceptual image coders that are based on DCT, which are compatible with the highly popular and widely adopted JPEG standard.

Download or read book Multimedia Signal Coding and Transmission written by Jens-Rainer Ohm and published by Springer. This book was released on 2015-03-16 with total page 563 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook covers the theoretical background of one- and multidimensional signal processing, statistical analysis and modelling, coding and information theory with regard to the principles and design of image, video and audio compression systems. The theoretical concepts are augmented by practical examples of algorithms for multimedia signal coding technology, and related transmission aspects. On this basis, principles behind multimedia coding standards, including most recent developments like High Efficiency Video Coding, can be well understood. Furthermore, potential advances in future development are pointed out. Numerous figures and examples help to illustrate the concepts covered. The book was developed on the basis of a graduate-level university course, and most chapters are supplemented by exercises. The book is also a self-contained introduction both for researchers and developers of multimedia compression systems in industry.

Download or read book The Role of Phase in Adaptive Image Coding written by Andrew G. Tescher and published by . This book was released on 1973 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report includes a detailed analysis of image modeling aspects of the transform coding problem. Two alternate prediction algorithms are analyzed for the transform sample variance estimation: the first technique uses a two-dimensional polynomial to model the image power spectral density; the second technique is a simple recursive approach based on previously quantized values. The generalized phase concept is developed and plays a vital role in the coding algorithms. Both the Fourier and Walsh transforms are used, the former being demonstrated to have superior performance. A non-negative image constraint is explored via the Lukosz bound. The experimental phase of the study includes two dimensional coding of monochrome, and three dimensional coding of color, as well as interframe images with coding at 0.38, 0.55, and 0.25 bits/pixel, respectively. It is demonstrated that adaptive transform domain modeling is important, and that large-size transforms, in conjunction with the proper image model, can significantly outperform block-encoding techniques.
