Survey on the latest development of pedestrian detection system and its key technologies expectation

Pedestrian detection system (PDS) is an active safety technique which guarantees pedestrians and vehicles safety. It has become a hot research topic and made good progresses in the latest 5 years with the development and application of sensor technologies, kernel algorithms and so on. Different with other PDS survey papers, this paper surveys the major works in this field during the last five years from the aspects of techniques and prototype systems; some problems are pointed out and analyzed to be solved. The expectation of the future work is given at the end.
