Abstract
Enhanced resolution video sequence results from construction of enhanced resolution key frames and synthesis of enhanced resolution non-key frames. Key frames are constructed by processing a plurality of initial resolution frames in order to produce the enhanced resolution image components of the key frame. Non-key frames are synthesized using the enhanced resolution image component of the key frames and image component motion determinations from initial resolution frames using an image warping technique. Non-key frame image components are further improved by blending and error correction processes.
