Summary:A method and a system of estimating a pose of a subject is disclosed. The method includes receiving a video stream from an imaging device in real-time; applying a trained computational model to extract feature maps from images received from the video stream; determining initial estimates of heatmaps and part affinity fields (pafs) from the extracted feature maps; refining the initial estimates of the heatmaps and pafs to output refined heatmaps and pafs; refining the heatmaps and pafs upon completing the refining of the initial estimates using a self-attention module; detecting keypoints on the heatmaps; and performing graph matching on the pafs to group the keypoints to different subjects.
