Abstract

A 2D complex Gabor-wavelet filter (CGWF) optical architecture based on the proposed Gaussian chirplet transform approach is presented together with its mathematical derivation. Far from the conventional setup schemes in which only the real part of the CGWF (even-symmetrical GWF) can be implemented optically, the proposed optical scheme shows that the real and also the imaginary part of the CGWF (odd-symmetrical GWF) can be achieved. The computer application simulations to the oriented edge feature extraction are given to validate the feasibility of the proposed scheme.
