MSU Video Super-Resolution Filter

Filter for high-quality video resolution enhancement

• Method ideas: Dr. Dmitriy Vatolin
• Implementation: Artem Titarenko

This filter increases resolution of video sequence while saving and improving details and reducing artifacts.

Main problems of the current approach:

• Fixed zooming factor (two times). Later it will be generalized.
• No scene change detection.

Characteristics

• Processing speed is considerably higher than for other SuperResolution approaches known to us
• Upscaling factor should be a power of 2. Other scaling factors are also possible, but they result in a relatively lesser quality of video due to use of additional common resampling algorithm
• Different presets with various speed/quality trade-off
• Processing is fully automatic
• Processing can be totally consecutive without look ahead at future frames
• There is a special algorithm for noisy video upscaling which gives smoother images of better visual quality

Examples

Since the output resolution of video is very large only parts of sequences are shown.

The first example is from “stefan” sequence:

AviSynth Bicubic	AviSynth Lancsoz4
Topaz Enhance SR	MSU Super-Resolution

The next example is from “news” sequence:

“news”, source video and video processed with MSU Super-Resolution filter

Fragment of the “toy” sequence:
