Shape matching using a curvature based polygonal approximation in scale-space
Antonio M. G. Pinheiro, Ebroul Izquierdo, M. Ghanhari · 2000
The emerging MPEG-7 standard demands shape description and shape retrieval techniques. Polygonal approximations of the shape contours give attractive solutions in this domain, because of the description simplicity. This paper introduces a shape matching technique based on the turning function comparison of the shape contour polygonal approximations.
