Paper Abstract

This paper describes the computation of the adapted normalization matrices as they were developed in the 'Structural Analysis and Coding of Images' study. In this study we had elaborated an adaptive compression method based on a parametrical segmentation of the images. After a training phase, for each defined parametrical class was associated a specific adapted normalization matrix to be used in the Discrete Cosine Transform (DCT) domain very much in the same way that the Joint Photographic Experts Group (JPEG) method performs its normalization. Obviously, the accuracy of the segmentation and of the matrix values are the critical points that determine the performance of this method.
