由于中亮度区域视觉效果方面表现最好，并且更加适合人眼观察物体，以对中亮度区域处理的过程为例。首先，用尺度为 的高斯函数 进行滤波运算，得到该区域的入射分量，然后从图像中去除入射分量，得到需要的反射分量，从而实现对中亮度区域的提取，此处将原图像 用亮度 替换其公式如下：

結果 (英文) 1:

Because the brightness range in best visual effects, and is more suited to the human eye the objects, to brightness of the regional process, for example. First, use scale for Gaussian functions for filtering operations, incident component of the region, and then removed from the image input component and get the reflection component, enabling the extraction of luminance range in here will be replaced with the brightness of the original image with the following formula:

結果 (英文) 2:

Because the brightness of the best performing regional visual effects, and more suitable for the human eye to observe objects to the process of regional processing brightness example. First, the scale function is a Gaussian filter operation to obtain a component of the incident region, and then incident on the component is removed from the image to obtain a reflection component needed to achieve the extraction of the luminance area, where the brightness of the original image is replaced with The formula is as follows:

結果 (英文) 3:

Because the visual effect in luminance region showed the best performance, and is more suitable for human eye observation object, to process the brightness disposal area as an example. Firstly, Gauss function is used as the scale of the filtering operation, incident components of the region, and then removing the illumination from the image, get the reflection component needs, so as to realize the extraction of brightness region, here the original image with brightness replace the formula is as follows:
