[1, Figure 2: Representation of Points in Clmtrackr Face Matrix]
Points 27 and 32 describe the centerpoints of the pupils. Currently, I am writing a software program that uses clmtrackr to detect faces in a videofeed. The software then measures the distance between the Point 27 and 32 and the four corners of each eye. If the length falls below a certain threshold, the program will know that the eye is in a certain corner.
