摘要：

The reproduction of natural objects in color images has attracted a great deal of attention. Reproduction of more pleasing colors of natural objects is one of the methods available to improve image quality. We developed an automatic color correction method to maintain preferred color reproduction for three significant categories: facial skin color, green grass and blue sky. In this method, a representative color in an object area to be corrected is automatically extracted from an input image, and a set of color correction parameters is selected depending on the representative color. The improvement in image quality for reproductions of natural image was more than 93% in subjective experiments. These results show the usefulness of our automatic color correction method for the reproduction of preferred colors.
