Video Processing

This was a commercial project for Sa'at Co and I think it is now used in their video archive program. They had streams of subscripted news with interleaved information screens and we needed to extract that information. Using a mix of openCV and the tesserect OCR engine this task was completed.

Also the program was to extract cut scenes, the point where the cameras changed. This seems easy, but footages taken by hand, and camera flashes, and fast cars passing near the camera, and heads bobbing in front of the camera, they make this task a nightmare!

One of the scenes that we had to detect and extract information from. I actually got this recently (Oct 2009), they seemed to have a problem with this particular one.
