Embedded moving image detection based on background subtraction and finite difference method

In the recognition of movement goal, this paper uses the serial port camera to acquire image data and capture image, both the frame difference and the background subtraction carry on the motion detection. In renewing the background, this paper also proposed to use a new approach which is based on the picture element and the probability density computation. The S3C2410ARM9 microprocessor is taken as the control core in the movement image observation system, the Linux system which is cut out analyses and researches image in the S3C2410ARM9 microprocessor.
