(mentor) Faculty Electrical Engineering, Mathematics and Computer Science Department Microelectronics & Computer Engineering Programme Embedded Systems Date 2011-08-30 Abstract There has been a vast improvement in Human-Computer Interaction over the last decade. Yet there are only a very few systems with natural interfaces such as with speech and gestures. This thesis here addresses the topic of gesture recognition using a 2D camera and how they can be used as natural interfaces to control applications. The gesture recognition algorithm can identify six different gestures and was first developed in a PC and later moved to an embedded platform. A robust background subtraction technique is designed to obtain the hand segment. Two gesture recognition methods are implemented, their performances are measured and the angle-based recognition approach is chosen for its accuracy. The application is moved to an embedded platform i.MX515EVK based on ARM Cortex-A8 processor. To obtain a frame rate suitable for real-time applications, optimizations such as camera capture time reduction, algorithmic optimizations and utilizing SIMD unit of the Cortex-A8 processor known as NEON for data parallelism are performed. As experimentation, the optimized version of the algorithm is used to build a real-time application that recognizes gesture from images to control applications. The performance of the application is studied and a frame rate of 4 - 4.5 frames per second is achieved.
