Opencv generally used for projects like face recognition bot or a bot that tacks certain objects. Control systems with augmented reality can be achieved like this.There can be a lot of future work and applications for this project. Instead of blue object we can use Haar cascade training and track hand movements. Then we can use gesture recognition so as to control home appliances according to specific hand movements Arduino has redefined cheap home automation. However the way of communicating with Arduino means entering commands from computer or via Bluetooth/WiFi . This project explores the possibility of controlling Arduino by using image processing through the open source platform ‘opencv’.
