【Abstract】This paper builds a vision sensor for occupant classification based on low cost CMOS camera and an intelligent pattern recognition
algorithm, which focuses on the 5th female(runty female) and the 50th male(average stature male), etc. The image pretreatment algorithm and
occupant image edge detection algorithm are founded. The critical properties of occupant edge are described by Legendre moment. The pattern
classifier based on the BP neural network is set up. The pattern classification of different occupant types is realized.
