Seminar Title: Vision-aided 3D Human Pose Estimation with RFID: Design, Implementation, and Generalization

Content (Video recording): Please find the seminar recording in


Brief Abstract: To In recent years, 3D human pose tracking has become an important topic in computer vision (CV). It is a more challenging problem than classification problems such as human activity recognition, and is the enabler of many human-computer interaction (HCI) applications. To improve the privacy of human pose tracking, there is considerable interest in techniques without using a video camera. To this end, RFID tags, as a low-cost wearable sensor, provide an effective solution for 3D human pose tracking. In this talk, we first present RFID-Pose, a vision-aided realtime 3D human pose estimation system based on deep learning. The RFID phase data is calibrated to effectively mitigate the severe phase distortion, and High Accuracy Low Rank Tensor Completion (HaLRTC) is employed to impute missing RFID samples. The system then estimates the spatial rotation angle of each human limb, and utilizes the rotation angles to reconstruct human pose in realtime with the forward kinematic technique. The second part of this talk addresses the user adaptation problem, when a well-trained system is used to monitor the 3D pose of a new subject. We propose Cycle-Pose, a user-adaptive realtime 3D human pose estimation system. A cycle kinematic network is proposed to remove the restriction in pairing RFID and vision data for training. The resulting system is user-adaptive, achieved by learning to transform the RFID data into a human skeleton for different subjects. The third part of this talk addresses the environment adaptation problem, when a well-trained system is applied in a new environment. Meta-learning, as an effective technique to improve the model adaptability, is leveraged as a promising solution to the generalization problem. We develop an RFID based pose estimation system, termed Meta-Pose, which is based on the meta-learning framework to address the generalization problem. The three systems are prototyped with commodity RFID devices and validated with extensive experiments, where high pose estimation accuracy and realtime operation are demonstrated.
