Hello,
I currently need to recognize different mouth shapes on photos (thin or thick lips, big or small mouth...). For now I have trained cascades for each mouth shape with about 30 photos of mouthes each (up to 1500 positive samples created with opencv_createsamples). The results are not convincing, the cascade for thin lips detects big lips and and vice versa.
So i wonder if cascades are the good way to do what I want or do I only need more positives samples?
I will also need to recognize the shapes of other face elements like eyes, eyebrows, nose... I am totally new to this technology, so has anyone already tried to do that? And how?
Thank you, Régis.
