Image Analysis by Discrete Orthogonal Hahn Moments
Orthogonal moments are recognized as useful tools for object representation and image analysis. It has been shown that the recently developed discrete orthogonal moments have better performance than the conventional continuous orthogonal moments. In this paper, a new set of discrete orthogonal polynomials, namely Hahn polynomials, are introduced. The related Hahn moment functions defined on thi...

متن کاملImage quality assessment by discrete orthogonal moments
This paper proposes a novel full-reference quality assessment (QA) metric that automatically assesses the quality of an image in the discrete orthogonal moments domain. This metric is constructed by representing the spatial information of an image using low order moments. The computation, up to fourth order moments, is performed on each individual ð8 8Þ non-overlapping block for both the test a...
متن کامل2D and 3D Image Analysis by Gaussian Hermite Moments
This chapter introduces 2D and 3D GaussianHermite moments and rotation invari-ants constructed from them. Thanks to their numerical stability, GaussianHermite moments provide better reconstruction and recognition power than the geometric and most of other orthogonal moments while keeping the simplicity of design of the invari-ants. This is illustrated by experiments on real 2D and 3D data. 7.1 ...
متن کاملImage analysis by discrete orthogonal dual Hahn moments
In this paper, we introduce a set of discrete orthogonal functions known as dual Hahn polynomials. The Tchebichef and Krawtchouk polynomials are special cases of dual Hahn polynomials. The dual Hahn polynomials are scaled to ensure the numerical stability, thus creating a set of weighted orthonormal dual Hahn polynomials. They are allowed to define a new type of discrete orthogonal moments. The...
