摘　　要：本文提出和实验了一种基于小波变换的区域纹理特征差值的变化检测方法,该方法通过小波变换提取区域纹理特征,而后采用差值求得其变化部分。实验结果表明,该方法对于高分辨率的遥感影像具有较好的检测效果,同时提高了运算速度,从理论和实践方面证明了该方法的可行性和有效性。This paper puts forward and experiences a method of difference texture feature based on wavelet for change detection.First by wavelet transform to two images,we get their approximation coefficients and detail coefficients,respectively,then extract texture features from above coefficients and find difference of them,finally process the inverse wavelet transform and get the changed region.This method detects change well and quickly for high-resolution remote sensing images,and results show its validity and feasibility.
