Hierarchical matching of deformable shapes
WebAbstract. This paper presents a method for matching closed, 2D shapes (2D object silhouettes) that are represented as an ordered collection of shape contexts [1]. Matching is performed using a recent method that computes the optimal alignment of two cyclic strings in sub-cubic runtime. Thus, the proposed method is suitable for efficient, near ... WebThis representation is based on a hierarchical description of an object's boundary and can be used in an elastic matching framework, both for comparing pairs of objects and for detecting objects in cluttered images. In contrast to classical elastic models, our representation explicitly captures global shape information.

Web28 de out. de 2010 · In this work we introduce a hierarchical representation for object detection. We represent an object in terms of parts composed of contours corresponding to object boundaries and symmetry axes; these are in turn related to edge and ridge features that are extracted from the image. We propose a coarse-to-fine algorithm for efficient … WebWe describe some techniques that can be used to represent and detect deformable shapes in images. The main difficulty with deformable template models is the very large or infinite number of possible non-rigid transformations of the templates. This makes the problem of finding an optimal match of a deformable template to an im-age incredibly …
