Abstract

An image coding scheme using a set of image visual patterns is introduced. These patterns are constructed to represent two basic types of image patterns (uniform and oriented) over small blocks of an image. The coding system characterizes an image by its local features, and further approximates each image block by a block pattern. Algorithms for pattern classification, computation of pattern parameters, and image reconstruction from these parameters are presented, and these provide the necessary tools for applying the proposed coding method to varius images. Satisfactory coded images have been obtained, and compression ratios in the order of 15 to 1 have been achieved.
