| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Unsharp masking is a common method of image sharpening. If unsharp masking is applied to each RGB component of a color image, the hue of the output image is changed from that of the input image. Hue preserving unsharp masking method has been proposed so far. However, the effect of the sharpening is a little low. In this report, we propose a new hue preserving unsharp masking method which sharpens the image effectively. In the proposed method, the component-wise unsharp masking is approximated by a linear transformation satisfying Naik's hue preserving condition. The gamut problem is resolved by a processing in an equi-hue plane in RGB color space. In the experiments, the effectiveness of the proposed method is verified by qualitative and quantitative evaluations. | |
