摘要
着重分析讨论了灰度级别、邻域信息对基于二阶互信息的配准技术的影响,通过实验分析得到在PV插值基础上最佳的灰度级别、邻域信息,从而改进了基于二阶互信息的配准技术,并借助分析噪声对配准的影响来解释相关结论。
In this paper, we studied the influence of grey levels and neighborhood information on the technology of image registration based on second -order MI from some experiments, getting the best grey levels and neighborhood information to improve this technology. At last, we analyzed the effects of noise on second-order MI to explain the conclusions in our paper.
