利用方向可控金字塔进行基于互信息的图像配准

Image registration based on mutual information using steerable pyramid

利用方向可控金字塔的方向可控性可以获取图像的方向信息,用来搜索最佳旋转变换参数,同时加入对平移量的搜索可以使这种方法能够处理具有平移和旋转变换的图像配准问题,采用互信息作为图像相似性度量的准则。实验表明该方法取得了较好的效果。

Using steerablity of the steerable pyramid, the orientation of the image could be obtained to search the best rotation transform, meanwhile the amount of translation could be searched together so that the method could deal with registration of both rotation and translation. Mutual information was used for similarity metric. Experiment results show that this approach performs well.
