The presence of oriented features in images often conveys important information about the scene
or the objects contained  the analysis of oriented patterns is an important task in the general
framework of image understanding. As in many other applications of computer vision  the general
framework for the understanding of oriented features in images can be divided into low- and
high-level analysis. In the context of the study of oriented features  low-level analysis
includes the detection of oriented features in images  a measure of the local magnitude and
orientation of oriented features over the entire region of analysis in the image is called the
orientation field. High-level analysis relates to the discovery of patterns in the orientation
field  usually by associating the structure perceived in the orientation field with a
geometrical model. This book presents an analysis of several important methods for the
detection of oriented features in images  and a discussion of the phase portrait method for
high-level analysis of orientation fields. In order to illustrate the concepts developed
throughout the book  an application is presented of the phase portrait method to computer-aided
detection of architectural distortion in mammograms. Table of Contents: Detection of Oriented
Features in Images   Analysis of Oriented Patterns Using Phase Portraits   Optimization
Techniques   Detection of Sites of Architectural Distortion in Mammograms
