Multichannel optical correlator for texture classification

We propose the use of a multichannel optical correlator working with two spatial light modulators for texture classification. The architecture may implement any method based on frequency filtering in the Fourier domain. The addition of linear phases in each filter shifts the filtered image in the co...
