Abstract: The invention relates to a method for image processing, which can be used to calibrate the background quickly. When the external environment is changed due to the switch of light, the color of background is calibrated quickly, and the background can be updated together. The method not only is used to update the background, but also can be used to eliminate the convergence of background again.

Abstract: The invention relates to a method for image processing. First, establish the initial image background information. And retrieve the instant image information. Then calculate the initial image background information and color intensity information of the instant image. Furthermore, adjust the instant image information. Then calculate the moving-object information. Finally, track the moving-object information. It can improve the accuracy rate of detection without the influence of erected height.

Abstract: A parking assistance system (PAS) comprising an image capture device, a display device and an image analysis device is provided, wherein the image capture device captures a rear parking image of a car and the image analysis device analyses the parking image to determine an initial line, two side lines and an auxiliary line in the parking image. The image analysis device determines a first reference point according to a specific position on the car, a second reference point according to an interval of the initial line between the two side lines, a third reference point according to an interval of the auxiliary line between the two side lines and a recommended parking path according to these reference points, and transmits the parking image and the recommended parking path to the display device, such that the parking image and the recommended parking path are superimposed to be displayed on the display.
