Smart Identity Recognition (SIR) group is affiliated to New Laboratory of Pattern Recognition (NLPR), State Key Laboratory of Multimodal Artificial Intelligence Systems (MAIS), Institute of Automation, Chinese Academy of Sciences (CASIA), led by Prof. Tieniu Tan and Prof. Zhenan Sun. SIR group concentrates on cutting-edge research of individual recognition, wherein the main focus is human-centric biometric recognition. The topics basically include biometric imaging device, data acquisition, preprocessing, feature encoding and matching, privacy and security. Iris recogntion, sclera recognition, face recognition, 3D human perception and action recognition and multi-modal fusion are covered in the research topics for developing more advanced SIR systems. Over the years, the members of SIR group are striving to conquer the key and difficult problems in non-cooperative individual recognition at a distance under complex scenarios, promoting the applications of SIR systems in surveillance, robotics and UAVs.
