The generation of high-resolution mosaics from multiple images is presented. The estimation of the high-resolution signal utilizes a motion-compensated filtering approach for video frames that are affected by spatial aliasing. For that, global motion models and the corresponding estimation algorithms are employed to provide a very accurate and continuous description of sub-pixel motion for the background of the video signal. The motion information is exploited to generate mosaics with four or sixteen times the resolution of the constructing video sequence or known mosaicing techniques. The mosaicing results indicate that the presented multi-frame methods provide superior visual quality. The approach is further extended to the generation of high-resolution video.
