Paper Abstract

We propose a method to evaluate the tolerance in color pattern recognition by multichannel correlation in the RGB system. For monocolor objects with equal shape on black background we define a range of recognition in the scene plane. The application of the range of recognition in the three channels gives the tolerance to color variations. As an application we study the tolerance of the recognition system to illuminant changes in the image acquisition. We use common lightings such as fluorescent, incandescent and daylight. The results show that the tolerance decreases for colors with a low contribution in at least one channel.
