Abstract: This paper presents fast optimal algorithm for approximation of a shape boundary with a polygon having minimum number of vertices for a given maximum tolerable approximation error. For this purpose, the directed acyclic graph (DAG) formulation of the polygonal approximation problem is considered. The reduction in computational complexity is achieved by reducing the number of admissible edges in the DAG and speeding up the process of determining whether the edge distortion is within the tolerable limit. The proposed algorithm is compared with other optimal algorithms in terms of the execution time.
