针对在遥感图像镶嵌中所产生拼接缝的问题，分析了现有的拼接缝消除方法，提出了直方图迭代匹配结合斜率改正比的消除方法。通过直方图的迭代匹配增强了图像的反差，在镶嵌的遥感影像中用斜率改正比的方法消除拼接缝实现图像的光滑过渡。实验结果表明，该算法具有很好的拼接缝消除效果并且减少了两幅图像的灰度差值和标准值差值，改善了图像的质量。

By analyzing the current Seam-Line Elimination(SLE),an improved method of Histogram Iterative Matching (HIM)combined with the elimination of slope correction-ratio is presented for image mosaic in remote-sensing image pro-cessing field. HIM is used for improving image contrast. Slope correction-ratio method is used for Seam-Line Elimination in smooth transition of mosaicking image.The experiment shows that the method minifies the gray scale&standard devia-tion of two original images and also improves the quality of output image.
