Abstract

We propose an iterative algorithm for the estimation of high resolution frames from a low resolution compressed video sequence. The algorithm exploits the existing correlation between the high and low resolution frames and the information provided by the encoder to obtain a high resolution frame. The performance of the algorithm is demonstrated experimentally.
