Image analysis is one of the most challenging areas in today's computer sci ence, and image technologies are used in a host of applications. This book concentrates on image textures and presents novel techniques for their sim ulation, retrieval, and segmentation using specific Gibbs random fields with multiple pairwise interaction between signals as probabilistic image models. These models and techniques were developed mainly during the previous five years (in relation to April 1999 when these words were written). While scanning these pages you may notice that, in spite of long equa tions, the mathematical background is extremely simple. I have tried to avoid complex abstract constructions and give explicit physical (to be spe cific, "image-based") explanations to all the mathematical notions involved. Therefore it is hoped that the book can be easily read both by professionals and graduate students in computer science and electrical engineering who take an interest in image analysis and synthesis. Perhaps, mathematicians studying applications of random fields may find here some less traditional, and thus controversial, views and techniques.

Markov random field (MRF) theory provides a basis for modeling contextual constraints in visual processing and interpretation. It enables us to develop optimal vision algorithms systematically when used with optimization principles. This book presents a comprehensive study on the use of MRFs for solving computer vision problems. Various vision models are presented in a unified framework, including image restoration and reconstruction, edge and region segmentation, texture, stereo and motion, object matching and recognition, and pose estimation. This third edition includes the most recent advances and has new and expanded sections on topics such as: Bayesian Network; Discriminative Random Fields; Strong Random Fields; Spatial-Temporal Models; Learning MRF for Classification. This book is an excellent reference for researchers working in computer vision, image processing, statistical pattern recognition and applications of MRFs. It is also suitable as a text for advanced courses in these areas.

Texture analysis plays a fundamental role in computer vision applications such as image understanding, object recognition, scene segmentation and so on. This thesis investigates novel types of high-order Markov-Gibbs random field (MGRF) models of images in application to texture recognition and retrieval. The goal is to discriminate a texture class represented by a single training (query) sample from other classes. Frequent in practice spatially variant perceptive (contrast/o set) deviations that preserve the image appearance hinder the recognition by signal co-occurrence statistics. Contrast/offset-invariant descriptors of ordinal signal relations, such as local binary or ternary patterns (LBP/LTPs), are efficient and popular means to overcome such drawback. The thesis explores the use of ordinal relations instead of more conventional signal co-occurrences or responses of filter banks used in today's MGRFs. Textured images are considered as samples from high-order ordinal models, which allow for learning, rather than prescribing characteristic shapes, sizes, and numbers of these patterns for texture recognition and retrieval. Approximate analytical estimates of the model parameters guide the selection of characteristic LBP/LTPs of a given order. The higher-order patterns are learned on the basis of the already found lower-order ones. The thesis introduces first the MGRFs based on complete ordinal relations of the signals. Because the cardinality of their set grows quickly, only up to the 4th{5th-order ordinal MGRFs remain feasible. Partial ordinal LBP/LTP-based relations have less limitations, so that higher-order models can be learned (up to 12th-order in this thesis) for representing textures. Comparative experiments on six databases confirmed that classi ers using multiple learned LTPs from the 8th{12th-order consistently outperform more conventional ones with prescribed fixed-shape LBP/LTPs or other local filters. The proposed learned models are mostly good enough to describe the textures. However, heuristic rules for feasible learning of the high-order models sometimes miss characteristic short-range dependencies. Adding the nearest-neighbour circular LTPs to the learned characteristic high-order LTPs overcomes this drawback and further improves the performance over the previous models. A learnable 5th-order LTP-based MGRF was also applied as a visual appearance prior for segmenting kidney images for automated medical diagnostics. Experiments confirmed that the proposed model outperforms two more conventional counterparts both qualitatively and quantitatively.

In the field of image compression, transmission and reproduction, the foremost objective is to reduce the amount of information which must be transmitted. Currently the methods used to limit the amount of data which must be transmitted are compression algorithms using either lossless or lossy compression. Both of these methods start with the entire initial image and compress it using different techniques. This paper will address the use of Markov Random Field Textures in image processing. If there is a texture region in the initial image, the concept is to identify that region and match it to a suitable texture which can then be represented by a Markov random field. Then the region boundaries and the identifying parameters for the Markov texture can be transmitted in place of the initial or compressed image for that region.

It enables us to develop optimal vision algorithms systematically when used with optimization principles. This book presents a comprehensive study on the use of MRFs for solving computer vision problems. The book covers the following parts essential to the subject: introduction to fundamental theories, formulations of MRF vision models, MRF parameter estimation, and optimization algorithms. Various vision models are presented in a unified framework, including image restoration and reconstruction, edge and region segmentation, texture, stereo and motion, object matching and recognition, and pose estimation. This second edition includes the most important progress in Markov modeling in image analysis in recent years such as Markov modeling of images with "macro" patterns (e.g. the FRAME model), Markov chain Monte Carlo (MCMC) methods, reversible jump MCMC. This book is an excellent reference for researchers working in computer vision, image processing, statistical pattern recognition and applications of MRFs. It is also suitable as a text for advanced courses in these areas.
