Abstract: General principles are presented which modify image processing techniques to give results in agreement with the visual perception of color images. To keep these principles and therefore the modified operations as simple as possible, the characteristics of the human visual system employed are limited to some psychophysical and uniformity features. This is done by making use of additive and uniform color spaces. In contrast with additive spaces, we have found that the uniform spaces introduce some problems in certain image processing techniques. A detailed study of three uniform color spaces indicated that the main problems are due to the increase in quantization error by the transformation from additive to uniform spaces. There is also an incorrect weighting in the distance function of the chromatic signals compared to the luminance contribution. Based on this study, solutions are presented to overcome these problems. Results of color smoothing operations and color edge detection are also given.
