摘要：
In this paper, we have proposed a new fast super-resolution 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.
