In this paper, we present a novel, fast, resolution-independent silhouette area-based matching approach. We approximate the silhouette area by a small set of axis-aligned rectangles. This yields a very memory efficient representation of templates. In addition, utilizing the integral image, we can thus compare a silhouette with an input image at an arbitrary position in constant time. Furthermore, we present a new method to build a template hierarchy optimized for our rectangular representationdoi:10.1007/978-3-642-14061-7_5 fatcat:hi2nuivymjb3hkejziynvyygsy
