Face detection in SimpleCV

Hi everyone, I recently decided to try simplecv and created a simple function that will detect faces in an image and print a box around them. I noticed though that it would not detect faces if i tilted my head or was not looking straight or even if a part of my forehead was hidden from the camera. Sometimes it even stopped recognizing faces even if i closed one of my eyes, or covered it with something. I was wondering, is there a way to fix this, as it is i believe a big issue when trying to recognize faces. Just realizing that i am new to the community and have already started complaining i want to say that you are doing a great job and that i really like how simple...simpleCV is, i definitely prefer it over matlab or octave when it comes to this kind of stuff.

Gleaf.

That behavior is pretty standard. The face detector we use was designed to only find full frontal faces. There are some that can handle a lot more variations.

Here is some suggested reading to help you understand why it does that:

Thanks for the links. I too hope SimpleCV improves in the future and be able besides its ease of use to also provide a number of great functions, i believe that is the way for it to become more popular and stand out from other similar software out there. Also a second book with more advanced topics or even better a section with user submitted functions (something like what mathworks or R have) would be great.
