By the popularization of HDTV, opportunities of watching high-resolution images on large-screen are increasing. For enlarging images, bicubic interpolation is widely used, but blur occurs. In this paper, we proposed super-resolution using IM-GPDCT applied to the compressed video. First, we considered the effect of padding the extended area in the process of IM-GPDCT. Second, IM-GPDCT was improved by using the difference of frequency distribution between magnification methods. The occurence of ringing was also suppressed. Finally, in addition to the IM-GPDCT applied to compressed video frames, using motion detection and multiple frames improved image quality. |
