An arithmetic coding is well known as a powerful and an interesting data compression techniques from information theoretic viewpoints. For the practical use, some fundamental problems such as an error propagation and an application to multi-valued images are remained to be settled. In order to apply this technique for the areas of multi-valued images, a simplified and a feasible method have to be developed.
In this paper, by introducing a bit plane decomposition and by employing the gray code representation instead of natural binary representation, for the image pixel, we present an effective and an executable procedures for medical X-ray images.
