title: Circular-Fourier-radial-Mellin transform descriptors for pattern recognition.
abstract: Image descriptors based on a circular-Fourier-radial-Mellin transform are proposed. They are invariant with respect to rotation, translation, and change of scale. They represent a generalized approach to specific descriptors using a circular-harmonic expansion, a Mellin transform, or moment invariants. The possibility of computing the Fourier-Mellin descriptors by using an optical processor in real time is discussed.
