Abstract

Chain codes are widely nsed for representing a line drawing digitally using connected short line segments. When the encoded image is presented in the usual way, the resolution is constrained by the grid size. Here we consider using a linear smoothing filter for improving the reconstruction accuracy. The linear reconstruction filter that minimizes the meansquare reconstruction error is derived, and it is found that subpixel accuracy can be achieved by using such a filter.
