Method and apparatus for detecting fog pedestrian movement behavior fast

The present invention provides a method and apparatus for detecting the behavior of a fast moving pedestrian fog. In the above method, within a video sequence for a predetermined time in the original image of each frame, respectively, perform defogging processing, after acquiring the defogging frame image corresponding to an original image; the original image and the frame corresponding to the pair of after the fog image are performed pedestrian detection, acquisition window containing pedestrians; for the later frames of the original image and the image corresponding to the fog, a window containing the pedestrian integrated pedestrian detection results obtained; according to each of the acquired characterized in pedestrian detection result obtaining motion in the video sequence pedestrian and the pedestrian is determined whether there is fast motion behavior according to the motion characteristics. By this technical solution, improve the detection accuracy of the pedestrian so that the fog run pedestrian detection more reliable.
