Image 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...
متن کاملImage 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 کاملFace Recognition Using Discrete Orthogonal Hahn Moments
One of the most critical decision points in the design of a face recognition system is the choice of an appropriate face representation. Effective feature descriptors are expected to convey sufficient, invariant and non-redundant facial information. In this work we propose a set of Hahn moments as a new approach for feature description. Hahn moments have been widely used in image analysis due t...
متن کاملImage Contrast Enhancement Using Discrete Dual Hahn Moments
The main objective of this paper is to develop a simple technique for contrast enhancement of monochrome and color images using Discrete Dual Hahn (DDH) moments. The basic idea of our approach is to measure a local contrast at each band of a DDH moment matrix and use it to modify them. These modified moments are used to construct the enhanced image by taking the inverse DDH moment transform. Fo...
