提出了一种基于图像频带一致性的多模态图像校准算法,该方法通过调整图像频谱的带宽,利用带宽调整后图像的强度对代替传统互信息定义中的图像灰度值,可以有效地克服互信息的局部极值问题。理论分析和实验表明该方法是可行、有效的。
A multimodal image calibration algorithm based on image band consistency is proposed. This method can effectively overcome the bandwidth of image spectrum and the intensity of image after bandwidth adjustment instead of the gray value of image in the definition of traditional mutual information Local Extreme Value of Mutual Information. Theoretical analysis and experiments show that this method is feasible and effective.
