In this paper, we propose a fast learning-based superresolution image reconstruction utilizing the Total Variation (TV) regularization method by eliminating redundancy of the reference database. We have achieved 114 times faster computational time compared with that of an ordinary learning-based method. It has been generally considered that the learning-based approach is difficult to be applied to the motion pictures because of its large computational time. We have implemented our system on the CELL processor, and studied a feasibility of applying our system to HDTV receivers. The computational speed we have obtained on the CELL processor is 202 times faster than that of the standard PC. This result indicates a possibility of applying our learning-based superresolution system to HDTV receivers.

In this paper, we have proposed a new fast superresolution magnification method utilizing the Total Variation (TV) regularization for HDTV receivers. The TV regularization approach has not been considered to be a practical technology for motion pictures because of its large computational time. We have solved this problem by applying a combination of a High-pass filter (HPF) and the simpler TV method to the TV up-sampling block in the conventional TV magnification system. The computational time has been drastically reduced by the proposed method without losing picture quality. We have implemented our system on the CELL processor, in order to examine the feasibility of SD to HD conversion in HDTV receivers. The result is successful that the computational time for one frame processing is 14.98ms, which is less than one frame time of 16.7ms.
