Abstract
AbstractHuman activity recognition (HAR) is a very challenging problem that requires identifying an activity performed by a single individual or a group of people observed from spatiotemporal data. Many computer vision applications require a solution to HAR. To name a few, surveillance systems, medical and health care monitoring applications, and smart home assistant devices. The rapid development of machine learning leads to a great advance in HAR solutions. One of these solutions is using ConvLSTM architecture. ConvLSTM architectures have recently been used in many spatiotemporal computer vision applications.In this paper, we introduce a new layer, residual inception convolutional recurrent layer, ResIncConvLSTM, a variation of ConvLSTM layer. Also, a novel architecture to solve HAR using the introduced layer is proposed. Our proposed architecture resulted in an accuracy improvement by 7% from ConvLSTM baseline architecture. The comparisons are held in terms of classification accuracy. The architectures are trained using KTH dataset and tested against both KTH and Weizmann datasets. The architectures are also trained and tested against a subset of UCF Sports Action dataset. Also, experimental results show the effectiveness of our proposed architecture compared to other state-of-the-art architectures.
