Recently, the Ministry of Education and the Academic Degrees Committee of State Council officially announced the evaluation result of National Excellent Doctoral Dissertations of 2011. There are totally 97 national excellent doctoral dissertations selected, and 256 more are nominated. Dr. Guofeng Zhang in our lab won the National Excellent Doctoral Dissertation Award. The title of his thesis is "Video Scene Reconstruction and Enhancement". His supervisor is Prof. Hujun Bao.
This thesis mainly focuses on solving the 3D geometry reconstruction and motion recovery problem from the real captured video data. By making use of information consistency and redundancy of video data, and leveraging the creative ideas of using keyframe representation and the complementary information from multiple frames, we propose a robust and efficient global optimization framework to deal with camera tracking, dense depth recovery, motion estimation, and video segmentation. It profits many applications, such as large-scale city modeling, autonomous visual navigation, video scene understanding and reusing, and mixed reality, all of which are regarded fundamentally important but difficult in the technical level traditionally.
