Regular moments for symmetric images
R. Paramesan, Ramaswamy Palaniappan, Sigeru Omatu · Electronics Letters · 1998
Symmetrical images in the x and/or y directions give zero values for odd regular moments, which cause classification problems. It is proposed that regular moments be computed from centres other than the image centroid, where the centre satisfies the translation, scale, rotation, and/or reflection invariance of regular moments.
