Method for segmenting multiple vehicles connected through shadows in video

The invention discloses a method for segmenting multiple vehicles connected through shadows in a video. The method comprises the following steps of: performing edge computing on a vehicle area of an image; then, performing comparison and judgment on images obtained after computing; removing outer contours of the shadows through edge information; and then, removing the shadows of the vehicles through a morphological method. As the edge information is mainly concentrated at the part of the outer contours of the shadows, the goal that the shadows are removed is achieved through image difference, and meanwhile, as the edge information of the vehicles is relatively rich, and moreover, the edge information is insensitive to illumination variations, the method has universality.
