| Abstract(in English) | We describe a silicon retina system for robust color detection against changes of illumination. A present model for color constancy is based on Land's retinex theory and opponent color theory. In this model, an input image is devided into red, green, and blue channels, and received by the image sensors with a logarithmic response. In each channel, the received image is filtered by a Laplacian-Gaussian spatial filter. And then, the opposite color responses, namely red-green and yellow-blue, are calculated. The specific color can be detected by specifying the area on the opponent color plane which is composed of two opposite color responses. We consider a hardware implementation of real time color vision system employing three wide dynamic range silicon retinas and FPGA. |
