| Abstract: | We proposed an image-coding algorithm with color constancy based on the center / surround (C/S) retinex model and the Naka-Rushton (N-R) equation; this equation was used in place of the logarithmic function used in the original C/S retinex model in order to encode the intensity information efficiently. Using images acquired at different periods of a day, we compared the output of our algorithm with the original C/S retinex algorithm. The results suggested that the N-R equation can improve the color constancy performance. |
