Unified manner: • multi-person detection • 2D pose estimation • instance segmentation • TO DO: • identify person instance • localize facial and body keypoint • estimate instance segmentation mask
Keypoint detection Produce heatmaps (one channel per keypoint), offsets(two channels per keypoint for displacements in the horizontal and vertical directions) points from the image position x to the k-th keypoint of the closest person instance j
Grouping keypoints into person detection instances • Mid-range pairwise offsets • Recurrent offset refinement • Fast greedy decoding
Instance-level person segmentation points from the image position x to the position of the k-th keypoint of the corresponding instance j
