Nonlinear Elastic Registration with Unbiased Regularization in Three Dimensions
We propose a new nonlinear image registration model which is based on nonlinear elastic regularization and unbiased registration. The nonlinear elastic and the unbiased regularization terms are simplified using the change of variables by introducing an [...]

The graph windowed Fourier transform: a tool to quantify the gyrification of the cerebral cortex
No opinion
The Gyrification Index (GI) quantifies the amount of folding of a cortical surface. In this paper, we show the efficiency of spectral analysis to perform such a task, and in particular we explain how the graph windowed Fourier transform can be used as a tool [...]
