Abstract

A human face identification system based on isodensity maps has been already proposed by authers. The isodensity maps are contours of isodensity areas, therefore they can be easily transformed into a chain code. By using chain-coded isodensity contours, improvement of the processing performance can be expected in terms of the processing time and the data size required.<br>When the isodensity contours are expressed by chain codes, however, the chain codes corresponding to one isodensity area are occasionally divided into several parts by only using a simple encoding scheme.<br>Consequently, in this paper, a new chain encoding method which is adequate for extracting isodensity contours is presented.
