A new method of hierarchical encoding is proposed, which is based on Arithmetic coding with Marcov models. In this method, a crude version of the image is transmitted first, and the details are added gradually, so that the receiver can quickly recognize the outline of the image. With this method, the coding efficency is about 15 percent better than with the standard coding scheme for facsimiles. The key technique is the special Marcov models for hierarchical encoding with which the pixels in the lower resolution level are also referenced.
