Paper Abstract

Two optical units who are constructed by one Fresnel transform and one lens can produce a scale fractional Fourier transform. The constraints between the tow units are analyzed. Based on that and fractional correlation theory, a scale distortion invariant pattern recognition method is proposed. Simulation results show that when a scale distortion input image can't be rightly recognized by the conventional correlation, it can be recognized well with the method. Deficiency of the method is that lots of matching filters are needed.
