The Computer Vision and Digital Art (CVDA) research group was founded in 2007 within the Institute of Digital Media at Peking University after I joined PKU. We focus on developing computational theories and models to solve challenging computer vision problems in light of biologically plausible evidences of visual perception and cognition. Our primary goal is to establish a mathematical foundation of understanding the computational aspect of the robust and efficient mechanisms of human visual perception, cognition, learning and even more. We also believe that the marriage of science and art will stimulate exciting inspirations on producing creative expressions of visual patterns.
