The facial landmarks estimator was created by using Dlibs implementation of the paper: One Millisecond Face Alignment with an Ensemble of Regression Trees by Vahid Kazemi and Josephine Sullivan, CVPR 2014. We use the blob detection algorithm, so we need to initialize the detector first. Usually some small objects in the background tend to be considered faces by the algorithm, so to filter them out well return only the biggest detected face frame: Also notice how we once again detect everything on a gray picture, but work with the colored one. A poor quality webcam has frames with 640x480 resolution. You need a different threshold. In order to know if a pixel is inside a pixel or not, we just test if the euclidean distance between the pixel location and the circle center is not higher than the circle radius. The purpose of this work is to design an open-source generic eye-gesture control system that can effectively track eye-movements and enable the user to perform actions mapped to specific eye .
