Curvature Regularization Via Weighted Nonlocal BiHarmonic For Image Processing
CUBE is a Nonlocal patch based image processing methods. CUBE(CUrvature regularization via Biharmonic Extension) tends to regularize the dimension and the curvature of the patch manifold at the same time. The key step of CUBE is solving a biharmonic equation on a manifold. We also introduced a weighted version of CUBE for the interpolating problem like image inpainting and semi-supervised learning.
