| 摘 要： | 提出了一种基于相关系数方法的遥感影像最佳拼接线的检测算法.该算法根据影像重叠区域内两幅影像对应像素的相关性来判别像素之间纹理差异,结合了影像亮度差异的信息,检测出的镶嵌线优于平分线法检测出的镶嵌线.以4幅相邻影像自动寻找镶嵌线为例进行了实验,取得了良好的效果,验证了算法的实用性与有效性. |

| Abstract: | This paper proposed a novel algorithm based on cross correlation function for detecting a stitching line in remote sensing images.The algorithm determines the texture differences among pixels based on the correlation of the pixels which belong to the overlap of the two images.Two sets of images were used to validate our method,and the experimental results showed the stitching line detected by cross correlation function was much better than that detected by normal method,which verified the feasibility and va... |
