Experiments on pattern recognition using invariant Fourier–Mellin descriptors
Yunlong Sheng, Henri H. Arsenault · Journal of the Optical Society of America A · 1986
Image descriptors based on the circular-Fourier-radial-Mellin transform are used for position-, rotation-, scale-, and intensity-invariant multiclass pattern recognition. The orders of the radial moments and of the circular harmonics are chosen to obtain an efficient image description. The first-order radial moments of three circular harmonics are sufficient to obtain a satisfactory recognition performance. The influence of additive noise is investigated. Experimental results are shown.
