Unable to detect pupil about gazetracking

[antoinelame]

Hi @maddy-nit

It's difficult for me to solve the problem without more information. You can contact me directly by email (available on my profile) so that we can work together on solving the problem. We need to dig deeper to get more information about errors in the algorithm. For the moment, the program is mainly calibrated according to my eyes and webcam. But we both have dark eyes, so you should normally have very good accuracy with the current algorithm.

We have to check:

• If there is no problem with Dlib’s facial landmark detector (shape_predictor_68_face_landmarks.dat). It's a good start to check if GazeTracking.eyes.frame_left is empty or not.
• If the threshold value in image_processing() method is correct according to your webcam/eyes

It should be fixed with the adding of auto-calibration (76aa16e).
