Abstract
Mobile phones are one of the most commonly used tools in our daily life and many people record videos of the various events by using the embedded cameras, and usually due to low resolution of the cameras, reviewing the videos on the high resolution screens is not very pleasant. That is one of the reasons that nowadays resolution enhancements of low resolu‐ tion video sequences are at the centre of interest of many researchers. There are two main approaches in the literature for performing the resolution enhancement. The first approach is multi-frame super resolution based on the combination of image information from several similar images taken from a video sequence (M. Elad and A. Feuer, PAMI, 1999). The second approach is referred as single-frame super resolution, which uses prior training data to en‐ force super resolution over a single low resolution input image. In this work we are follow‐ ing the first approach which is multi frame resolution enhancement taken from low resolution video sequences.
