Moving object detection method and a mobile detecting device

Even for an image including the subject such as a person whose shape moves while changing, providing a moving object detecting method capable of correctly region division. A step (S101) of accepting a plurality of pictures that constitute a moving picture, each block consisting of one or more pixels constituting the picture to detect the motion of an image between two pictures temporally adjacent , the detected motion by connecting the plurality of pictures, the step of calculating a step (S102 and S103) of calculating the movement trajectory for a plurality of moving track is calculated, the distance representing the similarity between the movement trajectory and (S104), among the calculated distance, and converts the geodesic distance by concatenating smaller distance than a threshold, detecting the discontinuity in the distribution of the resulting geodesic distance, than the detected discontinuous point and a step (S105 and S106) to the area division by the moving track at a distance smaller geodesic distance as one cluster. .FIELD 7
