Paper Abstract

A new design of the correlation filter is proposed. The spectral iterative technique and the Fourier-Mellin descriptor are used in the filter design. Targets are detected by rotating this filter in the Fourier plane to determine points of constant intensity. The results of computer simulation show that distortion (translation, rotation, scale, and intensity) invariant pattern recognition can be achieved.
