Abstract
With the recent development of cheap and accurate depth sensors, activity recognition research has largely focused on the use of features created from 3D, rather than 2D, skeletal joint location. Nevertheless, conventional 2D RGB cameras remain an attractive data collection tool due to their low cost and ease of use. This study investigates the benefits of using 2D skeletal joints for activity recognition using visualisation and an exemplar classifier. Results show that 2D models can be as informative as 3D models, demonstrating the informativeness of joints extracted from RGB video.
