Optical Flow Improved with HOG-based image descriptors Brox, T., Bruhn, A., Papenberg, N., & Weickert, J. (2004). High accuracy optical flow estimation based on a theory for warping. In Computer Vision-ECCV 2004(pp. 25-36). Springer Berlin Heidelberg. Brox, Thomas, and Jitendra Malik. "Large displacement optical flow: descriptor matching in variational motion estimation."

Stereo PDE formulation (with anisotropic diffusion smoothing), very similar to optical flow solutions: H. Zimmer, A. Bruhn, L. Valgaerts, M. Breuß, J. Weickert, B. Rosenhahn, H.-P. Seidel: PDE-based anisotropic disparity-driven stereo vision. Vision, Modeling, and Visualization 2008.

Image Registration Multimodal non-rigid registration: - reference, - target, - deformation For the multimodal problem a level-set / edge-based matching energy is used.
