灰度特征和空间结构是影像的两大识别特征,利用遥感影像中不同地类的纹理特征及灰度特性之区别,提取出有效的地类识别因子,应用动态规划理论综合考虑这些识别因子,找出不同地类的边缘.这种综合运用的方法可有效地检测出遥感影像中地类的边缘.“,”This paper presets the method of extracting ho category identifiable factor factor on different texture.and grey level features on remote sensing image, and using dynamic programming to detect the edge of different land categories. This method can detect edges of remote sensing images efficiently
