Face Hallucination via Gradient Constrained Sparse Representation
Face hallucination is an example of the image super-resolution problem, where the higher resolution face images can be obtained from the lower resolution ones. Many methods based on the sparse representation have been proposed to solve this problem. These methods use the position-patch strategy, whi...
