| Abstract;We present a wavelet transform-based template matching method to be able to deal with local boundary deformations of a two-dimensional shape. Template matching is one of the most important research subjects in image processing or image understanding. Particularly, in many industrial applications, a fast and flexible method is required to realize a practical matching system. In order to establish such a robust matching, in this paper, we describe both of a template and a target shape as Mallat's wavelet zero-crossings representations, and measure the dissimilarity between them by comparing amplitudes and intervals of these zero-crossing points. Since this algorithm adopts Mallat's dyadic wavelet transform, it can disregard local boundary deformations at the higher scales. And also, since the two-dimensional shape's information is translated into a one-dimensional description adequately, processing is very fast. Experimental results showed that our method performs well to both artificial and real images. (author abst.) |
