Patent ID: 8401232

Claim:
An object detection method of detecting one or more predetermined objects in a video, comprising: a step of obtaining plural kinds of detection results acquired by detecting the entireties or parts of the predetermined objects in a current frame according to plural kinds of object detection methods; a step of setting, based on predetermined detection accuracies corresponding to the plural kinds of object detection methods, initial probabilities of the plural kinds of detection results of the current frame corresponding to the plural kinds of object detection methods; a step of calculating, based on detection results of one or more moving objects in plural frames including the current frame, a movement frequency distribution diagram representing movement frequencies of respective pixels in the current frame; a step of filtering objects detected in a previous frame of the current frame based on the movement frequency distribution diagram so as to obtain filtered detection results of the previous frame; a step of updating, based on overlaps of the plural kinds of detection results of the current frame and the filtered detection results of the previous frame, the probabilities of the plural kinds of detection results of the current frame corresponding to the plural kinds of object detection methods; and a step of determining a final list of detected objects based on the updated probabilities of the plural kinds of detection results of the current frame.
