摘要
HIS变换法是根据人眼的视觉特性,把RGB彩色变换到HIS域,并且建立这样的假设,即亮度分量反映原图的亮度信息,色调分量和饱和度反映原图的彩色信息。这样亮度分量直接被高分辨率图像替换,融合效果就会具有较高的空间分辨率。
The method of HIS transform is to change the RGB colour to HIS region according to the visual features from people＇s eyes. And a hypothesis is proposed, the luminance component reflects the luminance information of the original picture and hue component and saturation reflect the colour information of the original picture. Th＇e luminance component is replaced directly by high resolution image, so the fusion has the effect of a higher space resolution.
