Non-rigid visible and infrared face registration via regularized Gaussian fields criterion
We analyze the robustness of Gaussian fields criterion both in theory and experiment. The Gaussian fields criterion is generalized from rigid to the non-rigid case. We propose a new non-rigid registration method to deal with more real-world problems. A sparse approximation on the transformation is applied to speed up the method. We customize and apply the proposed method to visible/thermal IR face registration.
