| 摘 要： | 小波变换在图像处理与分析方面的应用已取得很大的成功,如基于小波变换的图像编码、去噪、融合等,但在多时相的遥感影像变化检测方面的研究还很少.提出并实验了一种基于区域特征的小波差值变化检测方法,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.实验结果表明了该方法的可行性和有效性.

| Abstract: | The theory of wavelet transformation has been applied successfully at the aspect of image processing and analysis, such as image coding and fusion, but little study has been carried on for the change detection of multitemporal remote sensing imageries. This paper put forward and experienced an effective method of differencing regional texture feature based on wavelet for change detection. This method detected the change well and quickly for high-resolution remote sensing images, and results showed its validity and feasibility. |
