Paper Abstract

A review of the multichannel correlation methods applied to discriminate color objects with the logical operation AND is presented. The effects of the color CCD camera as the acquisition system are studied. A preprocessing method is proposed to increase the discrimination. The generation of the filters is improved by applying lithographic techniques. Finally an approach of the optimal filter proposed by Yaroslavsky is applied to each channel in the correlation process. Computer and experimental results are given.
