Abstract: This lecture is an approach dedicated to the improvement of color pattern recognition performances for computer vision. Like humans, the artificial intelligence systems use color for pattern recognition. There are a lot of systems for pictorial content representation and recognition based on color features. First section is dedicated to the evaluation of the color spaces for computer vision. One considers the conversion from the conventional RGB space into a color space with improved pattern recognition performances. In the second section, we present the model of Concurrent Neural Classifiers (CNC) representing a collection of small neural networks, which use a global winner-takes-all strategy. Each neural module is trained to correctly classify the patterns of one class only and the number of modules equals the number M of classes. One considers the case of choosing the SOM (Self-Organized-Map) as a neural module. We built M training pattern sets and each neural module is trained with the pattern set characterized by the corresponding class label. Third section has as theme data fusion for color pattern recognition as an emerging technology with significant advantages over simple source data . We consider data fusion and feature fusion for the channels of the considered color space. Fourth section is dedicated to the special technique of pattern recognition called decision fusion, by combining the classification powers of several classifiers. The combination function should take advantage of the strengths of the individual classifiers, avoid their weaknesses, and improve classification accuracy. We present the experimental results of our approach for color pattern recognition in the fields of biometrics and robotics.
