Image compression is concerned with minimization of the number of information carrying units used to represent an image. Lossy compression techniques incur some loss of information which is usually imperceptible. In return for accepting this distortion, we obtain much higher compression ratios than is possible with lossless compression. Salient features of this book include: four new image compression algorithms and implementation of these algorithms; detailed discussion of fuzzy geometry measures and their application in image compression algorithms; new domain decomposition based algorithms using image quality measures and study of various quality measures for gray scale image compression; compression algorithms for different parallel architectures and evaluation of time complexity for encoding on all architectures; parallel implementation of image compression algorithms on a cluster in Parallel Virtual Machine (PVM) environment.

Fractal image compression is an attractive technique for image coding because of its distinct features and the low bit-rate requirement. In this research, several techniques are introduced to improve the compression performance. Fractal image compression is based on the self-similarity search of the image. The encoding process is computationally intensive. In this thesis, a pyramidal framework is proposed to reduce the encoding complexity. The encoding complexity is reduced by as much as two orders of magnitude. Because the domain-range matching is independent, parallel methods are proposed to further speed up the encoding process. As with any lossy compression schemes, one of the challenges is either to maximize the image quality at a fixed bit rate, or to minimize the rate required for a given quality. To fulfil this purpose, the constant contractive factor in conventional fractal image compression is extended to the case of nonlinear contractive functions, which lead to significantly better reconstructed images and faster decoding than the conventional fractal method. Furthermore, as digital images and video products are designed for human viewing, human visual system (HVS) models are exploited to faithfully reproduce perceptually important information and eliminate the information that the visual system cannot perceive. Based on the human visual system's nonlinear response to luminance and the visual masking effects, a perceptually appropriate metric is defined. The psychophysical raw data on the visual contrast threshold is first interpolated as a function of background luminance and visual angle, and is then used as an error upper bound for perceptually based fractal image compression. The perceptually based method produces visually better reconstructed images than the conventional method and the JPEG standard. To reduce the domain search complexity, the pyramidal search method is also extended for perceptually based fractal image compression. Practical fractal image compression is a block coding. At very low bit rates, fractal method encoded images may exhibit blocking artifacts. Based on the Laplacian pyramidal representation of the image, the thesis presents a general post-processing method to remove the blocking effects.

This book presents the concept of fractal and its geometry with the explanation of how natural objects require different geometry rather than traditional Euclidean geometry and also discusses mathematics of fractals with the simulation results of generated fractal and applications of the fractal geometry in image compression.Image compression is minimizing the size in bytes of a graphics file without degrading the quality of the image to an unacceptable level. The objective of image compression is to reduce irrelevance and redundancy of the image data in order to be able to store or transmit data in an efficient form. Image compression using fractal has a major drawback of large encoding time and several algorithm have been developed to reduce the encoding time for compression. In this thesis various algorithms of Image compression using fractal are presented.

This book is concerned with the theory and application of fractal geometry in digital imaging. Throughout the book, a series of new approaches to defining fractals are illustrated, such as the analysis of the fractal power spectrum and the use of fractional differentials. Several new algorithms and applications are also discussed and applied to real life images. Fractal Geometry in Digital imaging will appeal to postgraduates, researchers and practitioners in image processing, mathematics and computing, information technology and engineering.
