Image analysis ... David Biedney

[thegreenman]

After reading this story in Wired about image analysis of al Quaeda videos at the Black Hat Security Conference, I thought I'd make sure you all saw the link to the software code the security consultant released to the public.
I'm sure this code could be helpful for novice investigators in analyzing supposed ufo videos.
The image analysis software source code is located here.


You probably already saw this but I couldn't find it via search of the forums.

Hope it helps..

EDIT: I just ran the code here on an image of myself and got the following data result:

I have no idea what these numbers or terms mean, maybe our resident expert could enlighten me?

I don't think David's going to have any insight on this random geeks program. If you read the article it tells you how to interpret the error levels.
