In this section, you can see RD curves, which show the bitrate/quality distribution of each SR+codec pair, and bar charts, which show the BSQ-rate calculated for objective metrics and subjective scores.
Read about the participants here.
You can see the information about codecs in the methodology.

Charts with metrics
You can choose the test sequence, the codec that was used to compress it, and the metric.
If BSQ-rate of any method equals 0, then this method should be considered much better than reference codec (codec with no SR).

Correlation of metrics with subjective assessment
We calculated objective metrics on the crops used for subjective comparison and calculated a correlation between the subjective and objective results. Below you can see the average correlation of metrics over all test cases.
In this section, you can choose the sequence, see a cropped part of a frame from it, shifted Y-PSNR visualization, and ERQAv2.0 Visualization for this crop. For shifted Y-PSNR we find the optimal shift for Y-PSNR and apply MSU VQMT PSNR to frames with this shift. See the methodology for more information.

SR+codec pairs leaderboard
The table below shows a comparison of all pairs of Super-Resolution algorithms and codecs.
Each column shows BSQ-rate over a specific metric. You can sort the table by any column.
All methods that took part in subjective comparison are ranked by BSQ-rate over subjective score. Other methods are ranked by BSQ-rate over ERQA.
If BSQ-rate of any method equals 0, then this method should be considered much better than reference codec.
If BSQ-rate of any method is striving to eternity (marked as '∞'), then this method should be considered much worse than reference codec.
"TBP" means that this SR+codec pair did not take part in subjective comparison.

SR+codec Benchmark Roadmap
|Feature||What it achieves||Release date|
|More test sequences||We will extend our dataset to make it more diverse and cover more
use cases. We expect it to contain 9×6×5=270 Full HD videos.
|We plan to conduct a bigger subjective comparison for all codecs
to get a more accurate ranking for more SR+codec pairs. The subjective
comparison with that many video pairs will be very expensive. If you
want to support our benchmark, please contact us:
|New Super-Resolution methods are constantly being developed.
We will add new qualitative SR methods to our benchmark
as they appear. We also expect developers to submit
their methods to us.
You can submit your method here.
|Enterprise report||We will compile an enterprise report with more test sequences
and different objective and subjective metrics. You can see
the example in the Report section.
|A new metric to
measure compressed video
|Subjective comparison showed that the most popular video quality
metrics — PSNR and SSIM — are not applicable to the
Super-Resolution task. We are researching our metric
for compressed video restoration quality that will correlate
well with subjective assessment.
|“Real-time” and “restoration”
|Some Super-Resolution models work faster than others, while slow
methods can achieve results of much better quality.
We plan to divide the leaderboard of our benchmark into 2 categories:
Submit your method
Verify your method’s ability to restore compressed videos and compare it with other algorithms.
You can go to the page with information about other participants.
|1. Download input data||
Download low-resolution input videos as sequences of frames in PNG format.
There are 2 available options:
|2. Apply your algorithm||
Apply your Super-Resolution algorithm to upscale frames to 1920×1080 resolution.
You can also send us the code of your method or the executable file
with the instructions on how to run it and we will run it ourselves.
|3. Send us result||
