MSU Video Quality Measurement Tool 2.7.1

MSU Video Quality Measurement Tool è un programma gratuito per la misurazione della qualità video. Questa applicazione consente di creare una comparazione obiettiva dei codec video ed eseguire i filtri di analisi video. Video quality is a characteristic of a video passed through a video transmission/processing system, a formal or informal measure of perceived video degradation (typically, compared to the original video). Video processing systems may introduce some amounts of distortion or artifacts in the video signal, so video quality evaluation is an important problem.



Main Features

Results are saved in *.CSV (can be opened everywhere)
All metrics are visualized (very useful for codec and filter debugging)
Main feature for codec lovers: comparative analysis.
Everybody in 5 minutes is able to demonstrate that one codec is better than another! It's easy:
Set "comparative analysis" and select original, sequences compressed with codec A and codec B (recommended more than 10000 frames).
Select metric (recommended Y-PSNR).
Select "Save bad frames" pairs of frames with maximum difference in values of the metric (A>B) will be detected and saved.
Press "Process", find output frames and select best pairs.
Upload frames to your favorite forum.
Done!
If you want to prove, that codec B is better than A just swap compressed files in metric form fields. Codec and filter developers can use this feature for tuning (fast codec/filter update testing).
Plug-ins interface gives user possibility to create their own metrics.
Masking (calculation of a metric for the part of a frame)
