Abstract
Since the traditional gamut compression algorithms will fail to consider the image spatial characteristics, a novel gamut compression method based on the image spatial characteristics is proposed in this paper. At first, the image is compressed by traditional compression algorithm, then the compensation values of lightness and chroma obtained by a high-pass filter are added to the compressed image. Finally, a gamut clipping processing is carried out. Experimental results indicate that the proposed method can not only guarantee the color features, but also preserve the image spatial characteristics quite well.
