Abstract: Databases of 3D shapes have become widespread for a variety of applications, and a key research problem is searching these databases for similar shapes. This paper introduces a method for ...

Abstract: In this work, we present a novel approach to extract rotation, translation and scale invariant shape descriptors for handwritten strokes. Invariant descriptions of shapes are useful for ...

Traditional approaches to estimate a scale invariant spatial scope for local image descriptors, a.k.a. characteristic scale, work well for intensity images. However, they fail when it comes to deal ...

Implementation of the SHOT algorithm introduced in "Unique Signatures of Histograms for Local Surface Description" by Tomari et al. Used to create a program to align shapes only partially overlapping ...

The shape of a cell as defined by its membrane can be closely associated with its physiological state. For example, the irregular shapes of cancerous cells and elongated shapes of neuron cells often ...

Large digital repositories of 3D models help create demand for search engines that are able to retrieve the data of interest and for data mining algorithms to discover relationships among them. Text ...

The matching and retrieval of the 2D shapes are challenging issues in object recognition and computer vision. In this paper, we propose a new object contour descriptor termed ECPDH (Elliptic Contour ...
