Visual Information Processing Group
The Visual Information Processing Group mainly focuses on the fields of Computer Vision and Multimedia, particularly covering the following research topics: (1) Novel visual computational theories and models based on the mechanism of human perception and cognition; (2) Robust and fast computational algorithms, particularly including reliable and fast algorithms for extracting 3D shapes from images; (3) Multimedia data processing, mainly including image/video analysis and processing; (4) Development of computer vision and graphics prototype systems that are of great practical value or market potential.

Visual Information Processing Group consists of two research teams

1. Robot Vision Group（visit Robot Vision Group）
The main research activities of the Robot Vision Group are concentrated on 3D computer vision, including camera calibration and 3D reconstruction, pose estimation, vision based robot navigation, and visual-serving etc. In this group, there are 4 full professors, 4 associate professors, and more than 20 Ph.D. students.

The group is mainly funded by the National Natural Science Foundation of China, the National 863 Program of China, the National 973 Program of China, and the Chinese Academy of Sciences.

Besides fundamental research, the group carries out vision applications in cooperation with the State Administration of Cultural Heritage, National Romote Sensing Center of China, National Astronomical Observatories, Nokia Research Center, etc.
