Wavelet Image Processing
Hyohoon Choi and Alan C. Bovik
7.1 Introduction
Multiresolution image representations using wavelet transforms have become
quite popular in recent years, owing to their effectiveness in a very broad array
of applications [1]. In essence, wavelets made it possible to formalize the general
concept of multiresolution processing that was being used, for example, in the
computer vision field to enable to detection, analysis, and recognition of image
features and objects over varying ranges of scales. Such important image pro-
cessing tasks as segmentation require that the image be analyzed over neighbor-
hoods of varying sizes in
