A Novel Non-Local Means Based Super-Resolution Algorithm with Back-Projection

A novel multi-frame super-resolution (SR) algorithm without explicit motion estimation is proposed. This method is intended to promote the precision of SR reconstruction by embedding the back-projection technique into the non-local means (NLM) based fusion and reconstruction process. Results on test movie show that the proposed method is very successful in providing super-resolution on general sequences and is able to remove the bur and edge artifacts effectively.
