Abstract

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. A hue-preserving unsharp masking method has been proposed thus far. However, the effect of image sharpening is slightly small. In this paper, we propose a new hue-preserving unsharp masking method that sharpens the image effectively. In the proposed method, componentwise unsharp masking is approximated by linear transformation satisfying Naik’s hue-preserving condition, and the gamut problem is solved by processing in an equi-hue plane in an RGB color space. In the experiments, the effectiveness of the proposed method is verified by qualitative and quantitative evaluations.

RGB颜色空间中等色调平面上的近似非锐化掩模
非锐化掩模是一种常见的图像锐化方法。如果对彩色图像的每个RGB分量应用去锐化掩模,则输出图像的色调与输入图像的色调不同。到目前为止,已经提出了一种保持色调的非锐化掩模方法。然而,图像锐化的效果稍小。在本文中,我们提出了一种新的保持色调的非锐化掩模方法,可以有效地锐化图像。在该方法中,通过满足Naik色调保持条件的线性变换来近似分量反锐化掩模,并通过在RGB颜色空间中的等色调平面中进行处理来解决色域问题。在实验中,通过定性和定量评价验证了该方法的有效性。
