I have an image of 480x360 px that contains eye portion only i.e., sclera iris, pupil, eyebrows etc. Now I have to find the lower eyelid in the image.
What I've done till now is that cut the image in 2 parts upper and lower half. Now apply edge detector (Canny) on lower part and then parabola fitting on the resultant image.
I am getting ok results but eyelid is not parabola so sometimes the parabola goes into the sclera region also.
I am thinking to doing curve fitting but a better idea looks like funding a curved line in the edge map.
Can you help in finding the curved line in the edge map ?
