Free utility for objective video evaluation

Hello,

I have developed an application that allows you to evalute the effect of compression or filtering between two video files. If you would like to read about video evaluation, a source with more information is this article.

If you would like to get straight to the download and the usage instructions, visit this page. The application is distributed for free.

The documentation is not exactly rich at the moment, so feel free to ask any questions or post comments.

Good luck!

Video Quality Studio 0.3 was just released with support for MP4 and MKV files.

Get it at http://www.everwicked.com/vqstudio/.

Important: Do NOT use the XviD DirectShow decoder to decode MPEG-4 video because it has a bug that will bogus results! Use ffdshow or 3ivx instead!

There's also the PDM Metric (Perceptual Distorsion Metric) that is supposed to be quite good. It has been tested on the VQEG set too, and been reported "better" than psnr. Want to implement it everwicked  ?

I haven't really searched it, but does this kind of stuff exist for audio too ? Any known "good" algorithms ?
It's a 'Jump to Conclusions Mat'. You see, you have this mat, with different CONCLUSIONS written on it that you could JUMP TO.

No one interested by my evaluation methods?
I know it is in french, but you should be able to understand the slides.

There are two problems:

1. As you said, it's in French. French is not franca lingua anymore and not many people understand it.

2. Requires IE to view, and can't download slides.

With these premises, did you expect anyone to read it?

1 should not be such a problem, as most of the slides should be easy to understand.
2 is a real problem and should be addressed
