The human ear is a perfect source of data for passive person identification in many
applications. In a growing need for security in various public places, ear biometrics seems to …

This paper details a comparative analysis on time taken by the present and proposed
methods to compute the Zernike moments, Zpq. The present method comprises of Direct …

This paper presents a novel approach to the fast computation of Zernike moments from a
digital image. Most existing fast methods for computing Zernike moments have focused on …

Discrete orthogonal moments have several computational advantages over continuous
moments. However, when the moment order becomes large, discrete orthogonal moments …

A Modified Direct Method for the computation of the Zernike moments is presented in this
paper. The presence of many factorial terms, in the direct method for computing the Zernike …

The definition of pseudo-Zernike moments has a form of projection of the image intensity
function onto the pseudo-Zernike polynomials, and they are defined using a polar …

Hand-based verification is a key biometric technology with a wide range of potential
applications both in industry and government. The focus of this work is on improving the …

This paper discusses possible computation schemes that have been introduced in the past
and cope with the efficient computation of the orthogonal image moments. An exhaustive …

Pseudo-Zernike moments have better feature representation capability, and are more robust
to image noise than those of the conventional Zernike moments. However, due to the …

Zernike moments (ZMs) have been successfully used in pattern recognition and image
analysis due to their good properties of orthogonality and rotation invariance. However, their …
