The impressive and continual progress in this field leads to application in uncooperative real-world scenarios such as detecting anomalous and dangerous behavior from individuals or groups within dense crowds in public places. However, reliably detecting poses within crowds in surveillance footage remains a very challenging task, due to diverse occlusions, illumination changes and long processing time. In this work, we present a simple Pyramid Vision Transformer for Human Pose Estimation achieving competitive results on the COCO Keypoints 2017 while requiring significantly less parameters and thus computation time. A significant improvement is reported over the baselines on the more crowded OCHuman, PoseTrack 2018, and CrowdPose datasets.enconference paper
