Head Positioning Technology In The Complex Environment Research And Realization

Intelligent monitoring system in the military, banking, transportation and other key sectors of the warning, security and modernization in the management of the needs and applications become more widespread. Vision-based video surveillance system is currently being widely used in traffic, bank and so on, the technology associated with it is paid more attention.Human head location technology research under complex environment is based on the current video images of the large number of surveillance data analysis and effective automated data extraction problems. At present video images of detection technology is receiving increasing attention, Sometimes the human body or part of it was obscured, the camera angle tilt or overlooking , in those situation we can not access to complete information to complete the face recognition and positioning. In this paper, we use human head location method to incomplete information when people face the loss goals.This paper investigates the moving objects on the base of the sequence of images, then locate human head with color and structural characteristic. Analyze the advantages and disadvantages of background generation algorithms technique, then presents a new group-update background generation algorithm and an improved multiple Gaussian model background generation algorithm. Using the current image and background images to extract moving target and then eliminate interference from the detected target. In the end, this paper use cirque-based Hough transform to locate human head by head shape features. When we meet the situation that the face is incomplete, this paper also analysis and achieve a human head location method based on the rapid detection.
