### Abstract

Most of the applications in image analysis are based on Freeman chain code. In this paper, the vertex chain code (VCC) proposed by Bribiesca is applied for estimating the length of the digitized 2D curve. The chain code has some preferences such as stable in shifting, turning, mirroring movement of image, and has normalized starting point. Due to the variety of length estimator methods, we focus on the three specific techniques. First is the way Bribiesca proposed which is based on counting links between vertices, second is based on maximum length digital straight segments (DSSs), and the last is local metrics. We then compare the result of these length estimators with the real perimeter. It is for the first that VCC is implemented in estimating the length of the digitized curve. The result shows that the estimation by applying VCC is near to the real length.
