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.

• 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。
