Abstract

In this paper we show different methods of defining and computing of colofulness of the image from digital image processing point of view. All experiments have been carried out on the set of natural color images with different perceptual colorfulness. We have tested the images using following simple colorfulness estimate based on statistical parameters of the pixel cloud along red-green and yellow-blue axes. During image processing the colorfulness of the image can be changed by increasing after color enhancement or by decreasing after image compression. Sometimes the colorfulness of the image should be invariant. We have presented it on examples, which show that the colorfulness can be useful for evaluating the color quantization algorithms beside such traditional performance functions as RMSE and ΔE .
