Scale invariant pattern recognition with logarithmic radial harmonic filters

Joseph Rosen, Joseph Shamir

A generalized approach leads to spatial filters that accept changes of scale by a factor of 4. The procedure employs phase filters with reduced tolerance requirements and achieves high discrimination capability and efficient light throughput. Computer simulations and laboratory experiments show the advantages of this novel approach.
