Available in PDF, EPUB and Kindle. Book excerpt: In order to utilize digital images effectively, specific techniques are needed to reduce the number of bits required for their representation. This Tutorial Text provides the groundwork for understanding these image compression tecniques and presents a number of different schemes that have proven useful. The algorithms discussed in this book are concerned mainly with the compression of still-frame, continuous-tone, monochrome and color images, but some of the techniques, such as arithmetic coding, have found widespread use in the compression of bilevel images. Both lossless (bit-preserving) and lossy techniques are considered. A detailed description of the compression algorithm proposed as the world standard (the JPEG baseline algorithm) is provided. The book contains approximately 30 pages of reconstructed and error images illustrating the effect of each compression technique on a consistent image set, thus allowing for a direct comparison of bit rates and reconstucted image quality. For each algorithm, issues such as quality vs. bit rate, implementation complexity, and susceptibility to channel errors are considered.

This book was released on 1991-11-30 with total page 762 pages. Available in PDF, EPUB and Kindle. Book excerpt: Herb Caen, a popular columnist for the San Francisco Chronicle, recently quoted a Voice of America press release as saying that it was reorganizing in order to "eliminate duplication and redundancy. " This quote both states a goal of data compression and illustrates its common need: the removal of duplication (or redundancy) can provide a more efficient representation of data and the quoted phrase is itself a candidate for such surgery. Not only can the number of words in the quote be reduced without losing informa tion, but the statement would actually be enhanced by such compression since it will no longer exemplify the wrong that the policy is supposed to correct. Here compression can streamline the phrase and minimize the em barassment while improving the English style. Compression in general is intended to provide efficient representations of data while preserving the essential information contained in the data. This book is devoted to the theory and practice of signal compression, i. e. , data compression applied to signals such as speech, audio, images, and video signals (excluding other data types such as financial data or general purpose computer data). The emphasis is on the conversion of analog waveforms into efficient digital representations and on the compression of digital information into the fewest possible bits. Both operations should yield the highest possible reconstruction fidelity subject to constraints on the bit rate and implementation complexity.

Available in PDF, EPUB and Kindle. Book excerpt: Vector quantization (VQ) is an effective spatial domain image compression technique which maps discrete k-dimensional vectors into a digital sequence suitable for communication or storage. This research investigates methods for improving the performance of vector quantization based on pyramid tools. An iterative optimization clustering VQ procedure based upon an initial codebook randomly sampled from the training set is presented. The main idea of the proposed algorithm is that a set of new cluster means is generated by using an iterative clustering algorithm, with the previous codewords as seeds. The training set is drawn from the present training images. The resulting cluster means are then used in a new codebook which is continually refined so that each iteration reduces the distortion involved in coding a given training set. The goal of such system is to reduce the bit rate so as to minimize communication channel capacity or digital storage memory requirement. This VQ can provide a reduction from 8 bits per pixel (bpp) to 2 bpp or 0.5 bpp with negligible degradation image quality. Vector quantization usually requires extensive computations. In this thesis both the pyramid processing and the fast algorithms are examined for vector quantization. After a brief introduction of the topic in Chapter 1, the history and fundamentals of vector quantization are presented in Chapter 2. Chapter 3 describes the concepts and techniques of pyramid image processing. A new VQ algorithm which is employed in the thesis is examined in Chapter 4. In Chapter 5 the importance of post-processing is emphasized with illustrative results. Even with post-processing the vector quantization method considered indeed provides a significantly better image compression over existing image compression technique.

Download or read book Image Compression Using Subjective Vector Quantization written by Ronny Quesnel and published by . This book was released on 1992 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The goal of this research is to improve the subjective quality of real world imagery encoded with spatial vector quantization (VQ). Improved subjective quality implies that a human perceives less visually objectionable distortion when looking at the coded images. Through study of several basic VQ schemes, the issues fundamental to achieving good subjective quality are uncovered and addressed in this work. Vector quantization is very good at reproducing quasi-uniform textures in an image, but has difficulty in reproducing abrupt changes in textures (edges) and fine detail and can cause a block effect which is subjectively annoying. A second generation coding scheme is developed which takes certain properties of the human visual system into account. A promising method which is developed utilizes omniscient finite state VQ, a new quadratic distortion measure which penalizes the misrepresentation of edges, and brightness compensation based on Steven's power law. The proposed subjective VQ is compared with several classical, first generation VQ methods." --
