WebWe describe a new hierarchical representation for two-dimensional objects that captures shape information at multiple levels of resolution. This 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. WebThis paper presents an approach to matching parts of deformable shapes. Multiscale salient parts of the two shapes are first identified. Then, these parts are matched if their immediate properties are similar, the same holds recursively for their subparts, and the same holds for their neighbor parts. The shapes are represented by hierarchical ...
CiteSeerX — 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 ...

WebIn this paper, we propose a novel object representation and matching algorithm based on hierarchical skeletons which capture the shape topology and geometry through multiple levels of skeletons. For object representation, we reuse the pruned skeleton branches to represent the coarse- and fine-grained shape topological and geometrical features. WebFigure 1. We process deformable shape pairs by two levels of hier-archy, local graphs and shape graphs. Such hierarchical structure offers a flexible and holistic shape representation that enables cor-respondence matching and provides rich features for an optimal transport matching stage. shapes.
