Firstly, according to this character, primacy central point is detected by the exploring extremum method in the windows of 3×3 pixels. Then, basing on this central point, approximate normal line at ±45°、0°and 90°angle are drew.if the minimums of normal line is at central point and the difference between the minimums and the maximum in the normal line is more than the threshold, this point is considered to the edge point of image.

首先，在3×3象素的窗口中，如果中心值为最小值，则以该点为基础，以±45°、0°和90°方向作为近似法线带，然后判断该法线上的象素最小值是否在切点上（即是否在法线的中心点上），再通过检验切点与轮廓法线上亮度极大值的差值是否超过阈值，来判断切点是否为边缘轮廓上的点。

Three TM/ETM+ image (1999, 2002, 2007) were used. Land use change areas were determined by using two change detection techniques of post-classification comparison and spectrum comparison. The resultant change images obtained by the two change detection methods were overlaid to obtain more accurate change information.
