I can find head and eyes coordinates. How can i recognize eyeglasses (borders) in opencv. I search a lot but i cant find a method for this. I dont want to use haar like recognition for find eyeglasses border because i try of opencv's haarcascade_eye_tree_eyeglasses.xml but its useless. Do you suggest me a method (like threshold , ...) or methods for this issue? (sorry for my terrible English writing)
