Fast Mesh-Based Medical Image Registration

no code implementations8 Nov 2014 Ahmadreza Baghaie, Zeyun Yu, Roshan M. D'souza

The minimization process was achieved using a mesh based discretization of the distance measure and regularization term which resulted in a sparse system of linear equations, which due to the smaller size in comparison to the pixel-wise registration method, can be solved directly.
