METHOD FOR AUTOMATICALLY DECIDING TRACKER SET ALONG OUTLINE AND STORAGE MEDIUM STORING PROGRAM FOR EXECUTION OF THE METHOD

摘要

PURPOSE: To easily detect the outline of a desired area to be extracted from an image without tracing the outline by deciding a combination of tracker candidate points to minimize the cost by means of a dynamic programming method with the selected one of plural initial points defined as a start point. CONSTITUTION: The initial points are positioned on a boundary of an initial area that is set to include a desired object to be extracted from an image (200). The distance between two adjacent initial points is set at the value less than the threshold by increasing the new initial points on the boundary (201). The inside of the initial area is scanned at every initial point to decide the tracker candidates (202). A combination of tracker candidates is decided to minimize the cost by means of a dynamic programming method among those combinations of tracker candidates and also to best show the outline of the desired object to be extracted (203). Then the tracker candidates are thinned to decide a tracker so that the distance set between the trackers is approximately equal to DT (204).
