Frequency-Domain Fourier-Mellin Descriptors For Invariant Pattern Recognition
Yunlong Sheng, Claude Lejeune, Henri H. Arsenault · Optical Engineering · 1988
Spatial-frequency-domain Fourier-Mellin descriptors are proposed for the determination of object orientation and for object classification. The new methods require neither segmentation of the input image from the background nor an image centroid. The effect of noise is analyzed. Experimental results are shown.
