Abstract
A method for recognizing a moving object includes receiving real-time video data from an image capturing device by an object recognition apparatus, extracting a first image at a first time point of the real-time video data by the object recognition apparatus, extracting a first background image from the first image, extracting a second image at a second time point of the real-time video data by the object recognition apparatus, wherein the second time point is after the first time point, updating the first background image to a second background image based on the second image, comparing the second image with the second background image to extract a moving object, and extracting the moving object.

- updating the first background image to a second background image based on the second image;
- comparing the second image with the second background image to extract a moving object;
- and
- extracting the moving object.
A method for analyzing an object flow, the method comprising:
- analyzing image data received from one or more image capturing devices to extract one or more moving objects from each image data by an object flow analyzing device;
- computing a velocity vector of the extracted one or more moving objects by the object flow analyzing device;
- clustering the one or more moving objects extracted into one or more clusters based on a direction and a magnitude of the velocity vector by the object flow analyzing device;
- selecting a central object among the one or more moving objects for the one or more clusters, respectively, based on the clustering by the object flow analyzing device;
- and
- determining a flow of the one or more clusters to which the central object belongs using a motion of the central object by the object flow analyzing device.
