Comparative studies of visual stimuli features affect the stimulus recognize

The experimental methods of psychology provides a basis of computer vision simulation,because it can reveal the law of human visual information processing. The shape and color are important features of stimulations, which are very crucial for the identification of stimulations. This study is based on the experimental psychology and BP neural networks, use experimental methods of reaction time measurements and feature extraction methods of the BP neural network, by the experiment of identifying three groups of geometric images of the same color in different shapes ,the same shape in different colors and shape and color are both different, and attempt to explore the relationships of affect of the stimulus recognition between shape features and color features of stimulations in the visual information process. Comparing and analyzing the experimental results getting from the experimental psychology methods, we can find that: in the image feature recognition, recognizing the shape feature is faster than the color feature.And the same experimental results obtained by BP neural network simulation.
