Human pose estimation task takes images as input and extracts a set of locations representing the predefined body joints and the sparse connections between the joints, called the body parts.A pose can be estimated from single or multiple frames, in a single (monocular) or multi-view (stereo) setup and for a single person or multiple people in the scene.In this work, we provide an overview of the classic and deep learning-based 3D pose estimation approaches.We also point out relevant evaluation metrics, pose parametrizations, body models, and 3D human pose datasets.Finally, we review stateof-the-art pose estimation results, briefly discuss open problems, and propose possible future research directions.
