MSU Super-Resolution Filter

Filter for high-quality video resolution enhancement

MSU Graphics & Media Lab (Video Group)

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:

Stefan Bicubic
AviSynth Bicubic
Stefan Lanczos4
AviSynth Lancsoz4
