| 摘 要： | 提出了基于熵的图像配准相似性测度的自动选取方法。基于熵的常用相似性测度，根据图像配准的要求提出了几种评价相似性测度性能的准则，即准确性、锐度性和快速性等。根据所提出的评价准则在MATLAB平台上对MR、CT和PET构成的单模态和多模态图像对自动选取适合的相似性测度，在低分辨率或噪声污染的情况下也选取出适合的相似性测度。实验结果验证了评价准则的可行性和有效性，避免了由于相似性测度选取不当引起的配准精度低。

| Abstract: | The protocols of automatic selecting the similarity measure based on entropy for image registration is presented.Some common similarity measures based on entropy are given firstly.The accuracy,the acutance and the celerity are put forwarded as rules to select the suit measure from these measures according to the requirement of image registration.The suit similarity measure is selected automatically based on our method for the unit-models and the multi-models of MR,CT and PET respectively in MATLAB,which is ... |
