图像替换去云的接缝消除研究

Image Exchange Seam Smoothing in Cloud Removal

利用影像替换的方法去除云层，是提高遥感影像信息的一种有效方法。但是，对于拼接线的消除，不产生影像突变效应是一个必要环节。本文介绍了基于小波变换的拼接缝消除方法及其改进方法一基于拼接线的接缝羽化消除法。该方法能够在影像局部替换完成后，更好地修正拼接缝附近的灰度差异，使之在拼接缝处的灰度有一个光滑的过渡。

Cloud removal by image exchanging is an effective method to improve the information quality of remote sensed image. A wavelet transformation - based break seam smoothing method and its improvement the seam eclosion method are introduced in this paper. This method makes a gray scale smoothing transition near the seam after an image exchanging.
