Image processing techniques can be very time consuming when applied linearly on the Central Processing Unit (CPU). Many applications require processing to take place in real-time. The Upper Body Pose Estimation and Recognition system developed by Achmed and Connan has shown to be 88% accurate, but operates at less than real-time on the CPU. This paper proposes an adapted version of this algorithm, which runs on the Graphics Processing Unit (GPU) to achieve real-time processing speed. The system was found to achieve a slightly improved recognition accuracy of 92.95% while achieving on average a real-time processing speed of no less than 18 Frames Per Second (FPS) and a mean speed of 33.26 FPS.
