The Complex Wave Representation of Distance Transforms
The complex wave representation (CWR) converts unsigned 2D distance transforms into their corresponding wave functions. The underlying motivation for performing this maneuver is as...

Laplace-Beltrami eigenfunction expansion of cortical manifolds
We represent a shape representation technique using the eigenfunctions of Laplace-Beltrami operator and compare the performance with the conventional spherical harmonic (SPHARM) r...

Shape retrieval using triangle-area representation and dynamic space warping
We present a shape representation and a matching method for nonrigid shapes with closed contours. The representation utilizes the areas of the triangles formed by the boundary poi...

A dynamic method for dominant point detection
Detecting dominant points is an important step for shape representation. Most of dominant point detection methods attend to preset or find the region of support of each point. In ...

MBC-based shape retrieval: basics, optimizations, and open problems
Shape of an object is an important feature for image and multimedia similarity retrievals. In our previous studies we introduced a new boundary-based technique (MBC-based) for shap...

Angular Histograms for Shape Retrieval
Distance histograms have been used for Shape Representation and Retrieval [1][2]. In this paper, we have proposed the use of angular histograms for shape representation. We have im...

BSP Shapes
We discuss a shape representation based on a set of disconnected (planar) polygons. The polygons are computed by creating a BSP that contains approximately linear surface patches ...

3D Object Recognition by Eigen-Scale-Space of Contours
People often recognize 3D objects by their boundary shape. Designing an algorithm for such a task is interesting and useful for retrieving objects from a shape database. In this pa...

An Efficient and Robust Technique for Region Based Shape Representation and Retrieval
Most region based shape image retrieval techniques in literature are complex to implement. As the result of their complex computations, the retrieval performance of these techniqu...
