空间加权互信息图像配准算法
Spatially weighted MI image registration algorithm
摘要
Abstract
A new registration algorithm based on spatially weighted mutual information (SWMI) was proposed. This algorithm used a Harris corner filter to classify the pixels of the reference image, and then we set different weights for the classification pixels according to their different contribution for image registration to generate the Harris weight (HW) function, which is used to calculate the SWMI. Compared to the original registration algorithm based on SWMI. Experiments show that this algorithm does not need manual directly intervention, so it is benefit for achieving automatic registration, it is very robustness and has a nice successful rate of registration.关键词
