Abstract

This paper proposes a comparative study of various super resolution (SR) techniques: Spectral approach, Interpolation and fusion, Wiener filtering, Maximum A Posteriori (MAP), Eigenfaces reconstruction and Projection Onto Convex Sets (POCS). MAP, Eigenfaces, Wiener filtering and POCS have been implemented and experimented on gray level images. We compare the performances of the algorithms on standard test protocols. The POCS and MAP give similar results. Blind SR [4], hybrid methods POCS-MAP and also the improvement of algorithms so that they can operate in real time are future directions for research work.
