Super-Resolution
Motivation
This project attempts to improve quality of images gained by digital still cameras. Resolution of current cameras is still not sufficient for some scientific purposes, but under certain circumstances it may be improved by using posprocessing methods known as Super-Resolution.
Description
Multiple images of a single unchanged scene are taken and a single image of a higher resolution is reconstructed by improved Super-Resolution method. The improvement is based on the knowledge of the processing that takes place within current off-the-shelf digital still cameras. Furthermore, registration (i.e. process of finding the shift coefficients) was significantly accelerated using GPU hardware.
