چکیده

We propose a Modi ed Fourier Descriptor and a new dis tance measure for describing and comparing closed planar curves Our method accounts for spatial discretization of shapes an issue seldom mentioned much less addressed in the literature The motivating application is shape matching in the Multimedia Analysis and Retrieval System MARS our content based image retrieval system The application requires a compact and reliable representation of object boundaries in the image database and a similarity measure that can be computed in real time We test our shape matching method on a set of Roman characters Results indicate that our method is a feasible solution for real time shape comparison

A Modified Fourier Descriptor for Shape Matching in MARS

We propose a Modiied Fourier Descriptor and a new distance measure for describing and comparing closed planar curves. Our method accounts for spatial discretization of shapes, an issue seldom mentioned, much less addressed in the literature. The motivating application is shape matching in the Multimedia Analysis and Retrieval System (MARS), our content-based image retrieval system. The applicat...

3 D face recognition using Contour , Fourier Descriptors

In this paper a contour matching based face recognition system is proposed, which uses “Fourier Descriptor of contour” for identification of faces. The feasibility of using contour and FD’s matching for human face identification is presented through experiment. The Fourier descriptor is used to describe the boundary of a shape in 2 dimensional space.The advantage of using the Fourier descriptor...

An Experimental Study on Various Combinations of Shape Descriptors and Matching Methods Applied in the General Shape Analysis Problem

The aim of the General Shape Analysis (GSA) is to find one or a few most similar general templates for a processed object — exact identification is not performed, but the general shape features are obtained. The GSA approach may be applied for coarse separation of objects in the database prior to their classification or in the case when the data are incomplete or there is a high variability wit...

New Pseudo-CT Generation Approach from Magnetic Resonance Imaging using a Local Texture Descriptor

Background: One of the challenges of PET/MRI combined systems is to derive an attenuation map to correct the PET image. For that, the pseudo-CT image could be used to correct the attenuation. Until now, most existing scientific researches construct this pseudo-CT image using the registration techniques. However, these techniques suffer from the local minima of the non-rigid deformation energy f...
