Shape descriptor for binary image retrieval

2016 IEEE 5th Global Conference on Consumer Electronics, 2016
Content-based Image Retrieval (CBIR) system search the images according to the image content such as color, texture, shape and others prominent features from the image. Among these features, shape can give visual structure and appearance of the image.

Fourier Shape Descriptors

2013
Fourier descriptors are an interesting method for modeling 2D shapes that are described as closed contours. Unlike polylines or splines, which are explicit and local descriptions of the contour, Fourier descriptors are global shape representations, that is, each component stands for a particular characteristic of the entire shape.

Efficient topological descriptor for shape representation

SPIE Proceedings, 2005
In a recent paper, we have introduced a topological descriptor for shape representation based on classical Morse theory. More precisely, given a manifold M and a Morse function f on M , we build an invariant [Morse Shape Descriptor (MSD)] of the manifold from the ranks of relative homology groups of all pairs of lower levels of the function f ...

A Continuous Shape Descriptor by Orientation Diffusion

2001
We propose a continuous description for 2-D shapes that calculates convexity, symmetry and is able to account for size. Convexity and size are known to be critical in deciding figure/ground (F/G) separation, with the study initiated by the Gestalt school [9] [11]. However, few quantitative discussions were made before.

Shape descriptors.

2012
Every day we recognize a numerous objects and human brain can recognize objects under many conditions. The way in which humans are able to identify an object is remarkably fast even in different size, colours or other factors. Computers or robots need computational tools to identify objects. Shape descriptors are one of the tools commonly used in image

Gaussian Shape Descriptor for Palmprint Authentication

Cognitive Computation, 2010
Single-modal biometrics has certain inherent problems such as noisy sensor data, non-universality of biometric traits, restricted degrees of freedom and the stability of the single algorithm itself. In order to overcome these problems and obtain a satisfactory recognition rate while maintaining high robustness, an effective solution is to employ multi ...
