This paper proposes a human activity recognition method which is based on features learned from 3D video data without incorporating domain knowledge. The experiments on data collected by RGBD cameras produce results outperforming other techniques. Our feature encoding method follows the bag-of-visual-word model, then we use a SVM classifier to recognise the activities. We do not use skeleton or tracking information and the same technique is applied on color and depth data.
Another method that was used for action recognition is based on features learned from 3D video data applying Independent Subspace Analysis (ISA) technique on data collected by RGBD cameras as in REF and they followed the bag-of-visual-word model and an SVM classifier to recognize the activities.
