We're trying to measure the distance from a pupil pixel to a glass frame.

Right now, we can obtain the pupil's position and the direction in which we need to search, using simple Dlib or OpenCV functions.

I'm considering using a line iterator to go down until we find the frame, but what would be the most robust way of detecting it? The goal is to get something like this

EDIT: I'm assuming I can always obtain this kind of picture quality

what's the technique used to detect the glass frame ? the distance between line and a point can be computed using this formula https://stackoverflow.com/a/39840218/4578111 – venkata krishnan Oct 30 '19 at 01:50
that's part of the question: what would be a robust way to detect it? – Tiago Abreu Oct 30 '19 at 11:10
that totally depends on how well you capture the face. any information on lighting conditions ? face positions ? – venkata krishnan Oct 31 '19 at 01:15
