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 comprising the steps of:obtaining a sequence of low resolution input frames containing different undersampled views of an optically imaged scene; and for each new low resolution input frame: 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.
