提出了一种基于Retinex和闭合边缘提取的新方法.这一方法对于彩色遥感图像中存在的阴影区域得到了增强.首先将彩色遥感图像利用小尺度Retinex进行增强,再利用边缘检测的结果,编制程序提取原图像中阴影的区域,将用小尺度Retinex增强的图像中相应的像素替代原图像中阴影的区域.在实施闭合边缘提取过程中,提出了真断点与准断点判别法、"蝌蚪"状尾巴回退消除法等,确保所需要的闭合区域的提取.这一方法对于遥感图像中地物的半自动提取方面有着重要意义.
提齣瞭一種基于Retinex和閉閤邊緣提取的新方法.這一方法對于綵色遙感圖像中存在的陰影區域得到瞭增彊.首先將綵色遙感圖像利用小呎度Retinex進行增彊,再利用邊緣檢測的結果,編製程序提取原圖像中陰影的區域,將用小呎度Retinex增彊的圖像中相應的像素替代原圖像中陰影的區域.在實施閉閤邊緣提取過程中,提齣瞭真斷點與準斷點判彆法、"蝌蚪"狀尾巴迴退消除法等,確保所需要的閉閤區域的提取.這一方法對于遙感圖像中地物的半自動提取方麵有著重要意義.

The research work has brought a new method, which is based on small-scale Retinex and closed regions extraction, to enhance color remote sensing image. The information in dark regions is highlighted using Retinex, and the closed regions of the remote sensing image are extracted after edge detection. The fused image is that the shadow regions in original image are replaced by the same regions of the handled image using Retinex. The new fused image has more information than which of original image. While the closed regions is being extracted, new programs to judge the real-broken points and the quasi-broken points were developed, to eliminate the tails of "polliwog" by the backspacing method, and so on. These methods play an important role for the objects of remote sensing images by the method of semi automatic extraction.
