Cai GuoQiang -, JiaDongYue · International Journal of Digital Content Technology and its Applications · 2011
Although t he current s tudy of face r ecognition ha s been ma de a lot o f a chievements r ecently, the performance o f face r ecognition existing h as some lim itation u nder m ovement conditi on, so it need s improvement or innovation continuously. Based o n a nalysis of ch aracteristics o f human face un der movement condition, this paper proposes a face recognition method based on VPM642, and discuses the key aspe cts. In t he detection of movem ent face, we ma ke c omprehensive use of th e image f rame difference and background difference method, and update background image in real-time. In the stage of face recognition, we use a simplified algo rithm for tem plate mat ching of r egional ener gy, reduce t he CPU co mputing time, and enha nce the real-time monitoring system further. U nder t he m ovement condition of 0.5m/s, the result shows that its recognition rate is 91% in 300 samples, its processing time is 100 ms, and reach the design requirements of face recognition under movement condition.
