Query: Double Sparse Multi-Frame Image Super Resolution   A large number of image super resolution algorithms based on the sparse
coding are proposed, and some algorithms realize the multi-frame super
resolution. In multi-frame super resolution based on the sparse coding, both
accurate image registration and sparse coding are required. Previous study on
multi-frame super resolution based on sparse coding firstly apply block
matching for image registration, followed by sparse coding to enhance the image
resolution. In this paper, these two problems are solved by optimizing a single
objective function. The results of numerical experiments support the
effectiveness of the proposed approch.
