Abstract:
In this paper, we introduce a new technique of color image quantization. It is carried out in two processing. In the first, we decrease the number of color using a multi-thresholding, by intervals, of the three marginal histograms of the image. In the second processing, the colors determined in the first processing are reduced by colors fusion based on the mean square error minimization. The algorithm is simple to implement and produces a high quality results.
