Paper Abstract

In this paper, we proposed two new contour coding techniques based on the arithmetic code, called block arithmetic coding and pre-processed block arithmetic coding. These techniques are intended to be used in the region-based image coding, and efficiently take advantage of the characteristics of the contour images. Blocks of pels in a contour image are treated as non-binary symbols. The efficiency of the binary arithmetic code is extended to coding of non-binary symbols via tree structured arrangement of binary arithmetic codes. The performances of the proposed techniques are compared with those of the techniques already reported, such as chain codes, READ codes, ordering techniques, and binary arithmetic codes. By computer simulations, the proposed techniques are shown to outperform any other existing technique.
