Eye detection using OpenCV Python

By Yerra Vijay Sai

We can also detect eyes and faces using OpenCV Python that which wee are going to learn in this tutorial.To achieve this we are using a trained model for eyes and face

Pre-request packages:

  For Detecting the eyes and faces on the webcam using Python you have to get the Haarcascade packages

haarcascade_frontalface_default.xml:

   For detecting the faces using OpenCV we have to use this XML file. 

haarcascade_eye.xml:

  For detecting the Eyes using OpenCV we have to use this XML file.

 

You can get the XML files by click here.

 

 Note:  

   We have to place the XML files in the same folder where our Python file will be or else you have to give the file destination whereever we are using.

 

Eye and face Detection Code: 

Step 1:

import cv2
import matplotlib.pyplot as plt
import numpy as np

 we have to import the OpenCV , Matplotlib,NumPy for detection of eyes and face

step 2:

cap=cv2.VideoCapture(0)

Giving  permission for webcam to capture the Video.

step 3:

 

face_cascade=cv2.CascadeClassifier('haarcascade_frontalface_default.xml')
eye_cascade=cv2.CascadeClassifier("haarcascade_eye.xml")

  Assigning the XML files using CascadeClassifier.
