Filters and comparisons downloads statistics
by MSU Video Group
One million filters and 200 thousand comparisons!
(CS MSU Graphics & Media Lab)

Group Leader: Dr. Dmitriy Vatolin

We had two anniversaries not long ago. There were 1 million downloads of both our filters and our programs. As a result, many students, ordinary users and researchers from various countries - e.g., USA, Germany, Italy, France, England, Poland and Australia (the list is far from complete) - send us their comments and suggestions.

It had taken us 4 years to gain the first million downloads, but we are able to gain another million in about 1.3 years. If the new generation of students will be quicker, then I think it can take even less (because new filters allow rapid increase of downloads).

So, we'll see what our young generation is capable of.

Another important borderline, which we overcame last July, is 200'000 of downloaded video codec comparisons. During these 4 years 11 codec comparisons were published. These comparisons cover practically all promising contemporary codecs. Moreover, number of downloads were assessed on the basis of traffic and not on the basis of access, thus this figure really shows the amount of downloaded comparisons (the sum is more than half a terabyte).

The frequency distribution of different comparisons' downloads is the following:

Index Title Downloads
1 H.264 Comparison 2006 31227
2 H.264 Comparison 2005 30539
3 MPEG-2 Comparison 2005 25481
4 H.264 Comparison 2004 23656
5 Old Test 2003 22627
6 MPEG-4 Comparison 2005 18033
7 WMPhoto 2006 13815
8 JPEG-2000 Comparison 2005 11373
9 Subjective Comparison 9837
10 Lossless Comparison (old) 8337
11 Lossless Comparison 2007 7161
Sum
202086

The obvious leader is the annual comparison of H.264 codecs. The dynamics of public interest to this comparison are very curious: each time a new comparison is released, the amount of downloads for old comparisons increases as well (which is quite natural, if to think of it); however, downloads of new comparisons grow even more rapidly, which means that there is a great public interest in them.

The dynamics are the following:

  • The first-year comparison was downloaded 23.5 thousand times in 2.5 years
  • The second-year comparison was downloaded 30.5 thousand times in 1.5 years
  • The third one was downloaded 31.2 thousand times in 0.5 years

However, download frequence functions in each period are pretty uniform (which is a drawback of our advertising). For example, 24% of downloads of the second comparison were during the first third of its period, 36% - during the second, 30% - during the third part.

We have similar situation with comparisons of codecs without losses: during first 28 months there were 8 thousand downloads, however 7 thousand downloads of the new comparison were made in 4 months.


Of course we understand what we can do better (for example, sometimes quality level of student filters is not so perfect), but, to the best of our knowledge, we are the only university multimedia lab which publishes video filters not as a MATLAB code. Enjoy! :)

Public MSU video filters
Here are available VirtualDub and AviSynth filters. Commonly we develop a whole family of some kind of a filter. Generally there are also versions optimized for PC and hardware implementations (ASIC/FPGA/DSP). These optimized versions can be licensed to companies. Please contact us for details via video(at)graphics.cs.msu_ru.
MSU filters for companies
We are working with Intel, Samsung, RealNetworks and other companies on adapting our filters other video processing algorithms for specific video streams, applications and hardware like TV-sets, graphics cards, etc. Some of such projects are non-exclusive. Also we have internal researches. Please let us know via video(at)graphics.cs.msu_ru if you are interested in acquiring a license for such filters or making a custom R&D project on video processing, compression, computer vision.
