This filter magnifies video sequence while saving and improving details and reducing artifacts. Its work is similar to MSU Video2Photo filter effect, applied to entire video sequence.
The main problems of current approach:
The primary examples can be seen on the MSU Video2Photo filter page, here only some video sequences are showed. The DivX 4.12 codec in the Quality-based mode was used for compression.
Since the output resolution of video is very large only parts of sequences are shown.
The first example is from the "foreman" sequence:
AviSynth Bicubic | AviSynth Lanczos4 |
Topaz Enhance SR | Proposed SR |
The next example is from the "news" sequence:
source frame of 'news' movie and frame processed with MSU Super-Resolution filter
A frame of the "toy" sequence:
source frame of ''toy'' movie and frame processed with MSU Super-Resolution filter
"foreman", source video and video processed with MSU Super-Resolution filter (340 KB, AVI)
"news", source video and video processed with MSU Super-Resolution filter ( 974 KB, AVI)
"toy", source video and video processed with MSU Super-Resolution filter ( 660 KB, AVI)
