根据图像的背景强度和灰度值跳变率将各像素的亮度分为不同区域，使用背景强

根据图像的背景强度和灰度值跳变率将各像素的亮度分为不同区域，使用背景强度以及梯度信息对图像进行二维分解，从而将图像的像素根据亮度划分为不同的区域。其中背景强度 需要其邻域像素的加权值得到：

結果 (英文) 1:

Against the background of the image intensity and gray value jump rate the brightness of each pixel is divided into different zones, using strength and gradient background information on decomposition of two-dimensional images, which according to the brightness of the pixel is divided into different areas of the image. Strength be the weighted sum of its neighbor pixels worth of background:

結果 (英文) 2:

According to the intensity of the background image and the gray value of the transition rate of the luminance of each pixel is divided into different areas, the use of the background intensity and gradient information of the two-dimensional image is decomposed, so that the luminance pixels of the image is divided into different areas. Where the background intensity needs of its neighboring pixels weighted worth to:

結果 (英文) 3:

According to the background intensity and gray image value jump rate will be brightness of each pixel is divided into different regions, the use of background intensity and gradient information of image two-dimensional decomposition, so will the pixels of the image according to the brightness is divided into different zones. The background intensity weighted needs of its neighborhood pixels is worth to:
