MSU Video Quality Measurement Tool: SDK

Plugins & Plugin SDK

• Front SDK
• Back SDK

Front SDK

Front SDK is a toolset that allows you developing you own metric to use in MSU VQMT.

Front SDK is free and can be used with all versions of MSU VQMT since version 1.2 (Free, PRO, Premium, and also available for Windows, Linux). To build your own plug-in, you should make a C-compatible shared library for the corresponding operaton system.

We also have several opensource plug-in samples, of real plug-ins of MSU VQMT:

• MSU Brightness Independent PSNR (BI-PSNR) - opensource
  This metrics allow to compare codecs correctly, even if one of them have changed average brightness of the frame.
• MSU Drop Frames Metric (DFM) - opensource
  Calculates number of dropped frames.
• MSU Brightness Flicking Metric (BFM) - opensource
  Estimates level of flicking.
• MSU Noise Estimation Metric (NE)
  Metrics Noise Estimator is intended for calculation of noise level for each frame of video sequence.
• MSU Scene Change Detector (SCD)
  Scene Change Detector is made to automatic identification of scene boundaries in video sequence.

Back SDK

Back SDK is aimed to companies who wants to integrate it's own products with MSU VQMT metrics. MSU VQMT Back SDK allows you effective (singlethreaded or multithreaded) usage of all metrics of MSU VQMT and image transformations inside your application.

VQMT SDK is provided as Linux shared library. VQMT back SDK compatible with C/C++, you can download interface here:
