RESEARCH PROJECTS

Surveillance of a crowd of pedestrians in public places like squares and subway stations is a challenging issue to public security. The crisis might lurk in the motion of crowd. To deal with the above-mentioned problem, we establish a modeling approach called “crowd modeling” and have built up a series of surveillance systems for testing.

We present a low–cost surveillance system to model and analyze human actions based on leaning by demonstration. By teaching the system the difference between normal and abnormal human motions, the computational model built inside the trained machines can automatically identify whether the newly observed behaviors require security interference.
