Here, we have used violajones algorithm for face detection using matlab program. Face recognition has been a fast growing, challenging and interesting area in real time applications.
There are different types of algorithms used in face detection. It detects facial features and ignores anything else, such as buildings, trees and bodies there are two types of face detection problems. Neural networks include simple elements operating in parallel which are inspired by biological nervous systems. The example detects the face only once, and then the klt algorithm tracks the face across the video frames. To save cropped picture you need to change the folder location. If a face is detected, then you must detect corner points on the face, initialize a vision. Tests made on a standard database show that the algorithm works very fast and it is reliable.
