Image registration algorithm based on motion vectors estimation
一种基于移动向量估计的图像配准技术

The goal of image registration is to align or match different images of the same scene and remove the potential geometric distortion existed. An algorithm of image registration based on motion vectors estimation was proposed. The algorithm takes advantage of complex wavelet transform (CWT) over the conventional wavelet transform, such as shift-invariance and better directional selectivity, to estimate motion vectors. The experimental results demonstrate that our proposed algorithm has very good performance in removing geometric distortion.
