Fast Generalized Motion Estimation and Superresolution

Abstract

We propose a new superresolution algorithm based on a fast motion estimation technique. Two stages of this algorithm, namely, motion estimation and high-resolution reconstruction, rely on an area-based interpolation scheme that involves intersecting two pixel grids in arbitrary orientation, displacement, and scaling. We develop a fast approximate solution of the above problem, whose exact solution is prohibitively expensive. Also, gradient descent algorithm is used for fast convergence of the motion estimation algorithm. Experimental results demonstrate the good performance of the proposed superresolution algorithm as well its robustness against noise.
