Real time face detection robot

Face tracking in real-time is required for activity recognition, automotive safety, and for surveillance systems. For this Arduino is used along with the packages available in MATLAB using Kanade-Lucas-Tomasi (KLT) algorithm. However, due to more complex motion in real time, a better algorithm is required. In this paper, the entire process is divided into two steps: the face is detected by Viola-Jones detection algorithm and then the KLT algorithm is used to track the feature points in the video frame. Human faces are detected and tracked with the help of webcam and servo motors. Thus, an efficient, low cost, light weight programmable robot has been built.
