A weighted robust estimating algorithm with high accuracy
一种高精度的加权鲁棒估计算法

In this paper, a cost function related to residual errors was introduced, and a weighted robust algorithm was presented. Firstly, the geometric transform matrix from the original data was calculated. Weight could be gained from the gray information around the key points. In the process of fitting the model of matrix, the optimal registration relation of the two pictures was found. Experimental results are of better satisfaction, better robustness and stronger sense of reality. It is highly valuable in practice.
