Density-based traffic light control using OpenCV

Human computer interaction is essential part of daily life. Hand gesture recognition is main implementation in this field. This project signifies a problem of controlling hospital's bed position by using hand gesture. If the patient is alone in a hospital room and no one present with him/her to change the position of bed then a patient can change the angle of bed by using hand gesture. To perform this action in a real time, we need an interactive application for hand gesture recognition. For this real time system webcams are used which create computer vision system and enable hand gesture method for human computer interaction. DC motor is connected with Arduino UNO kit and patient's bed which will change the position of bed with respect to recognized hand gestures. The system is based on Open CV library and image processing methods. Our goal is to demonstrate a real time system to change the positions of bed by hand gesture signs using a webcam and simple hardware components.
