Abstract: A moving object is detected from a movie. The actual movie has a complicated background. In order to detect the moving object, the invention is constructed to comprise, in addition to means 500 for inputting the movie, and display 300 for outputting the processed result: means 700 for judging the interval which is predicted to belong to the background as to a pixel region in the movie; means 800 for extracting the moving object; and means 900 for calculating the moving direction and velocity of the moving object.Thanks to the above-specified construction, even under the complicated background in which not only the change in the illumination condition but also the structure change will occur, the presence of the structure change of the background can be judged to detect/extract the moving object on real time. Moreover, the moving direction and velocity of the moving object can also be calculated.

Abstract: The present invention is intended to provide an image recognition method which, in recognizing an input image including an object presumable to have continuity like a human figure, enables simultaneously detecting the shape of the object in the input image and cutting-out the object therefrom, and obtaining information on position of the object at the same time, and which also enables recognition of two objects having the same shape but having different sizes.

Abstract: A moving object is detected from a movie which has a complicated background. In order to detect the moving object, there is provided a unit for inputting the movie, a display unit for outputting a processed result, a unit for judging an interval which is predicted to belong to the background as part of a pixel region in the movie, a unit for extracting the moving object and a unit for calculating the moving direction and velocity of the moving object. Even with a complicated background in which not only a change in illumination condition, but also a change in structure occurs, the presence of the structure change of the background can be determined so as to detect and/or extract the moving object in real time. Additionally, the moving direction and velocity of the moving object can be determined.
