Single-Camera 3D Human Pose Estimation: Addressing Occlusion Challenges and Predictive Quality Assessment

Published:14 March 2024Publication History

ABSTRACT

Human Pose Estimation, or HPE, pertains to the process of precisely determining the spatial coordinates of distinct anatomical segments of the human body depicted within an image frame. This challenge has garnered significant attention over the last decade and is poised to remain a focal point in the future. Beyond its significance within the scientific community, this field holds practical implications for applications such as augmented reality, military operations, and surveillance of densely populated areas. The present study concentrates on the intricacies of 3D HPE using a single 2D camera. The exploration encompasses the accessibility of data, prevailing metrics pertinent to this endeavour, and the complications introduced by occlusion. A specific focus is placed on introducing a methodology to evaluate the accuracy of predictions for visible and occluded key points in scenes characterized by corresponding visibility conditions. Promising outcomes are obtained, as the accuracy of predictions for visible key points remains consistent even in the presence of occlusion affecting other key points. Furthermore, a prospective avenue of research is proposed, involving the identification of occluded key points through the analysis of high-frequency noise incorporated into joint positions over temporal intervals. To conclude, an analysis is provided concerning both the challenges and opportunities inherent in this research endeavour.
