SYSTEM AND METHOD FOR ANALYZING IMAGE, AND IMAGE ANALYSIS PROGRAM RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To make outputable information on the states of stablly tracing objects and the union and separation of a plurality of objects by introducing a diversity such as one-to-multiple and multiple-to-one to the correspondence relation among objects between image frames. SOLUTION: The position and size of an object are acquired from an image area occupied by the object in respective image frames constituting an image, then, the transition cost in the case where the object in the former frame moves to the object in the latter is calculated about the set of the objects on the two frames in regard to the objects detected in the two adjacent frames, the correspondence relation between the objects on the two frames is classified from the transition cost, and the state of the objects is decided. The moving track of an individual object is traced over a plurality of image frames in the above correspondence relation of the objects by utilizing the information of results obtained by performing calculation about all adjacent inter-frames in the section of the image composed of a plurality of image frames.
