Paper Abstract

A full-fledged Visual Pattern Image Coding system is developed. For high compression ratio, Uniform Patterns are merged by Quadtree merging. For high visual quality, a new set of 2 X 2 Edge Patterns are designed for near perfect reconstruction. By a classification scheme of 11 groups or a threshold of gradient magnitude, the performance profile can adapt to a wide variety of applications.
