摘要 基于互信息量的图像配准算法只考虑单个相对应点间的关系,忽略了图像的空间信息,因此当图像分辨率较低、有噪声影响和部分缺损时就容易出现误配。将图像的空间信息引入到配准中,考虑对应点及其邻域的关系,提出了一种新的相似性测度——高维互信息量。新的测度不仅能够反映图像的灰度统计信息,而且能够反映图像的空间信息。实验结果表明,在图像空间分辨率较低、有噪声影响和图像部分缺损的情况下,该算法具有较高的准确性。 Mutual information (MI) is calculated on a pixel by pixel basis. It takes into account only the relationship between corre- sponding individual pixels and not those of each pixel's respective neighborhood. It ignores the spatial information. A new measure-high dimention mutual information is proposed. It is an extension to the mutual information framework which incorporates spatial infor- mation about image structure into the registration process and has the potential to improve the accuracy and robustness of image registration. The results indicate that co-occurrence mutual information is a more robust similarity measure for image registration than MI.
