自适应阈值分割程序，对遥感图像进行二值化处理后提取出水体-Adaptive threshold segmentation procedures, the remote sensing image binarization processing to extract the water body

水体的像素值的范围是由图像的光谱信息决定的, 通过阈值提取水体。。(The range of the pixel value of the water body is determined by the spectral information of the image, and the threshold is segmented.)

很简单的基于灰度阈值提取全色影像水体的代码(A very simple extraction of water body code from panchromatic image based on gray threshold)
