Quaternion moments and their applications to color images

Overview

The codes are corresponding to a chapter “Quaternion moments and their applications to color images” of an open-access edited book titled “Recent Progress in Image Moments and Moment Invariants”. The book will be published by Science Gate Publishing. These codes are performed in Matlab2017.

Description of the codes

(1) The codes are based on a toolbox “qtfm” provided by Dr S. J. Sangwine et al. (http://privatewww.essex.ac.uk/~sjs/). Please add it to path before performing codes;

(2) To implement Quaternion Zernike Moment Invariants, please run Main_QZMIs.m in the folder “Quaternion Zernike Moment Invariants”;

(3) To implement Quaternion-type Moments, please run Main _QTMs.m in the folder “Quaternion-type Moments”;

(4) To implement Quaternion Gyrator Transofrm, please run QGT.m;

(5) For Quaternion Bessel-Fourier Moments and Its Descriptor, see folder QBFMs for details. To compute QBFMs, please run QBFMs_Decomposing.m;To compute quaternion Bessel-Fourier moments, please run QBFMD_Fast.m.
