Abstract: A method of people counting in videos based on the double _ellipse mode can calculate the number of people of crowed and partially occluded aims at the situation where inviroment and background are complex First abstract outline of the moving object and shape the outline to a ellipse,then fitting the ellipse of a head in the outline according to prior knowledge. If the shape and the head all can be successfully fitted to cllipses,we can simplcly determine a human body. When crowed is dense, separate the moving target in advence, then recognize them. This method is suitable for vertical mode, tilt mode, distant view mode, nearby view mode of camera lens, and can count the number of people on the basis of identifying the human body and the non-human body.
Key words: People counting, Ellipse fitting, Least sctuare method, Hough transform
