Multi-Task Head Pose Estimation in-the-Wild [PDF]
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2021 We present a deep learning-based multi-task approach for head pose estimation in images. We contribute with a network architecture and training strategy that harness the strong dependencies among face pose, alignment and visibility, to produce a top performing model for all three tasks.
