Hello to all! I'm looking for an example (as simple as possible) to do the face detection. I found this tutorial: http://dasl.mem.drexel.edu/~noahKuntz/openCVTut11.html but I get this error: error: could not convert '{{0, 0, 255}}' from '<brace-enclosed initializer="" list="">' to 'CvScalar' how to solve? or otherwise: you know a better tutorial? thanks :)
