Paper Abstract

Many applications require a complex processing, using for it a bank of filters. Different architectures have been proposed of optical processors to perform a parallel filtering. We prose a new multichannel architecture based in the translation Fourier Transform properties. These properties allowed us to design multichannels phase filters. The architecture does not need the introduction of any additional modification in the optical processor. We developed an application for texture classification in real time. We obtain excellent results in the texture classification process, 99 percent of images have been correctly classified.
