- W2361741447 abstract "Image registration based on mutual information is of high automatization and high accuracy in registration. Hence, it has been widely exploited in medical image registration. Mutual information functions are often unsmooth. There are lots of local maximums, which abversely obstruct optimization algorithms. In this paper, features of mutual information functions are discussed and a hybrid algorithm combined by PSO and Powell is proposed. Experiments show that this hybrid algorithm could efficiently restrain local maximums of mutual information function.Also the registration accuracy could be improved to sub-pixel level." @default.
