Opencv (Open source computer vision) is a python library that will help us to solve computer vision problems. This is the equation to calculate the EAR using the six parameters of the eye : We can use the given function to calculate the EAR : This is the most important part, when you calculate the EAR of an eye, it remains constant when the eye is open but it suddenly drops when the eye is blinked. We saw that we can extract any facial structure from the 68 Facial Landmarks that we detected. Ajax Open it in raw format, right click and save. When the eye is looking straight the sclera is well balanced on left and right side. Better results are obtained by using high quality images and increasing the amount of stages for which the classifier is trained. C We can either read a single image file or use frames from a video. Basically, this ratio gives us a certain relation between the horizontal and vertical measurements of the eye. Next: Well keep the count of the frames when the EAR is lower than the threshold and if the count is 3 (or 5 depending on the fps) frames then well consider a blink detected. Use eye_cascade.detectMultiScale(). O.S. I have written following script for the same: import numpy as np import cv2 face_cascade = cv2.CascadeClassifier ('haarcascade_frontalface_default.xml') eye_cascade = cv2.CascadeClassifier ('haarcascade_eye.xml') cap = cv2.VideoCapture (0) while True .
