Abstract
A method of processing low resolution input frames containing undersampled views of an optically imaged scene to produce a higher quality, higher resolution output frame. This method operates by obtaining a sequence of low resolution input frames containing different undersampled views of an optically imaged scene. With regard to each new low resolution input frame, the method involves the further steps of measuring a displacement between a previous low resolution input frame and a new low resolution input frame to sub-pixel precision to produce a measured displacement; coarsely registering a high resolution working frame with the new low resolution input frame based on the measured displacement; finely registering the new low resolution input frame with the high resolution working frame by expanding the new low resolution input frame into a new high resolution input frame based on the measured displacement; and merging the new high resolution input frame into the high resolution working frame to produce an output frame.
