I am doing my research on lip detection and recognition. I am using Open CV with Visual studio 2010 c++. I want to detect the lips in image. When I load the image in opencv how can I differentiate that image quality (Noise, Lightening, contrast and shadow) is ok for detection for lips before starting the image processing?

It is hard to say... You should start testing with different kind of images and see which one is the best. What I can say is that very noisy/lightening, or shadows may influence the detector in a bad way

It depends on your recognition algorithm, it's condition of usage, etc. how to say that a priori?
