Medical Image Registration Algorithm Based on Laplacian Spectrum
Xia Yuna · Jisuanji gongcheng · 2011
The medical image registration algorithm based on Laplacian spectrum algorithm is proposed.The idea of using graph theory as medical image point registration is proposed.By eigenvector,the higher registration precision and the strong ability have been achieved.The Laplacian spectrum of the anatomy feature point sets of the two images is constructed to match.The strategy uses the homogeneous matrix,coordinate transfer and the image interpolation to register.Experimental results show that it has more efficiency and higher registration precision than maximization of mutual information whenever in the single sensor or multi-sensor.
