Abstract: An algorithm for polygonal approximation based on local integral deviation is presented. The algorithm is tested on various shapes with varying number of dominant points. A comparative study of the proposed procedure with other iterative methods shows that the proposed procedure produces polygon from a digital curve approximating high as well as low curvature regions with almost equal precision.

Keywords: digital planar curve; dominant points; iterative point elimination; sum of squares of deviation; polygonal approximation; local integral deviation.
