What’s new

15.07.2021 Improved Visualization section to be more user-friendly and added plots with the metric difference on BI and BD degradation to Leaderboard section.
21.05.2021 Added new plots to Charts section.
26.04.2021 Beta-version Release

Key features of the Benchmark

New metrics for the detail restoration quality
- Check methods’ ability to restore real details
The most complex content for restoration task: faces, text, QR-codes, car numbers, unpatterned textures, small details
- See plots and visualizations for particular content types
Different degradation types to lower the resolution: bicubic interpolation (BI) and Gaussian blurring and downsampling (BD), with and without noise
- Many methods use only one degradation type for their training datasets (e.g. bicubic interpolation) and do not work well on others. Choose the method that didn’t overfit the test dataset
Subjective comparison of new and popular Super-Resolution methods

The test-stand of the benchmark: the captured frame and the frame divided by content types.
See methodology for more information.

Leaderboard

The table below shows a comparison of Video Super Resolution methods by subjective score and a few objective metrics on Bicubic interpolation (BI). Default ranking is by subjective score.

You can see information about all participants here.

Metric: Test: Content:

Highlight the plot region where you want to zoom in

Visualization

In this section, you can choose a part of the frame with particular content, see a cropped piece from this, MSU VQMT PSNR* Visualization, and ERQAv1.0 Visualization for this crop. In part "QR-codes" codes, which can be detected, are surrounded by a blue rectangle. You can see information about all participants here.
*We visualize shifted PSNR metric by applying MSU VQMT PSNR Visualization to frames with optimal shift for PSNR.

1. Download input data		Download input low-resolution videos as sequences of frames in .png format There are 2 available options: a. Download 1 folder with all videos, joined in one sequence here. Neighboring videos are separated by 10 black frames, which will be skipped for evaluation. b. If you worry this strategy can decrease your performance, you can download 12 folders with 100 frames each here.

2. Apply your algorithm		Restore high-resolution frames with your algorithm. You can also send us the code of your method or the executable file and we will run it ourselves.

3. Send us result		Send us an email to vsr-benchmark@videoprocessing.ai with the following information: A. Name of your method that will be specified in our benchmark B. Link to the cloud drive (Google Drive, OneDrive, Dropbox, etc.), containing output frames. Check that the number of output frames matches the number of input frames: 1310 frames in one folder for download option (a) 12 folders with 100 frames each for download option (b) C. (Optional) Execution time of your algorithm and information about used GPU D. (Optional) Any additional information about the method: 1. Full name of your model 2. The parameter set that was used 3. Any other additional information 4. A link to the code of your model, if it is available 5. A link to the paper about your model 6. Any characteristics of your model's architecture (e.g. motion compensation, propagation, fusion)
