Face Recognition with 20 ~ 30 degrees Horiz./Vert. orientation

Question

I have a dataset about 1000 face images in size, I need to use a face recognition algorithm that recognizes these faces, plus for horizontal / vertical orientation of 20-30 degrees, the algorithm should still fulfill that best approach / algorithm that will help me in completing this task. I need to create a .NET api / dll for a task, I think about using OpenCV, and then wrap it in .NET. I need speed, so I have to resort to OpenCV, if in .NET there is nothing better.

Any helpful recommendations are highly appreciated.

thanks

Answer 1

I am not an expert on this issue, but I work in graduate school with two other videos and image processors, and I believe that they used the Trace Transform algorithm, as well as several other algorithms for that.

Here is a link that contains a couple of article articles and sample source code: http://www.face-rec.org/algorithms/#TRACE

Hope this helps!
