I have looked on many online project that use opencv mediapipe and dlib and all of them don’t really get very accurate about identifying a shut eye.
The facemesh always shows some distance between the eyelids even when the eyes are completely shut.
The vertical line is non-zero even though it should be zero what the eye is closed.
This unfotunately is not accurate enough for my needs (dry eye clinic therapy).
Is there a way to get a more accurate measure of the closed eye?
