Abstract

This paper presents a restoration scheme of gray level image which can generated more smooth-dithered and less blurred image. Our scheme embeds local area information on each dithering block into the image to get a high quality image. When a dithered image is sent for facsimile in this scheme, the received image can be output as a normal hardcopy and be displayed on the terminal CRT as more clearly softcopy, using the embedded information.
