IMPORTANT: In order to compile this files you need the OpenCV module, you can download from http://opencv.willowgarage.com/wiki/Getting_started?action=AttachFile&do=view&target=FindOpenCV.cmake

NOTE: When compiling you could have problems with a cvconfig.h, apparently this is a OpenCV bug but only need copy this file to your OpenCV's include directory.
