Hi,
Can someone please explain the difference between Mattes et al Mutual Information MMI and Viola and Wells Mutual Information VMI?
From the description in the links, I understand that MMI uses Parzen histogram with a user-defined number of pins ( it is not clear what is the difference between Parzen window and Parzen histogram?). MMI uses 3rd-order BSpline kernel for only the moving image (in Viola and Wells it uses Gaussian kernel for both images).
Thanks
