A new approach for pattern description is presented. Based on a multi-scale analysis of closed contours, this method deals with the differential turning angle extracted from a progressively smoothed contour to generate the differential-turning angle scale space (d-TASS) map. Experimental results show that the d-TASS map is closely related to the contour and it is resistant to affine transformation and so well-suited for pattern description.
