Abstract

In this paper, we contribute to the existing body of knowledge of video indexing technology by presenting a novel approach for recognition of tennis strokes from consumer-grade video cameras. To classify four categories with three strokes of interest (forehand, backhand, serve, no-stroke), we extract features as a time series from stick figure overlays generated using OpenPose library. To process spatiotemporal feature space, we experimented with three variations of LSTM-based classifier models. From a selection of publicly available videos, trained models achieved an average accuracy of between 97%–100%. To demonstrate transferability of our approach, future work will include other individual and team sports, while maintaining focus on feature extraction techniques with minimal reliance on domain expertise.
