RUSSIAN VERSION

Drop Frame Metric
(DFM)

MSU Graphics & Media Lab (Video Group)

Project, Ideas: Dr. Dmitriy Vatolin
Implementation: Alexey Noskov

 

Common description

DFM is made to calculate number of drop-frames in sequence.

 

Visualization

Metric's visualization difference of Y-planes between two consecutive frames + 128. So, grey color (128 128 128) means that brigtness of a pixel is the same as at the previous frame.

 

Plots

Metric's plot is making after all measurements. "Zero" value means that current frame exist, "one" - that it is dropped. The resulting metric's value is number of drop-frames.

Plot's example:

 

Algorithm

For each frame difference with the previous one is calculating. Metric's value is 1 if frames are identical, 0 otherwise.

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.
