Abstract
A spatiotemporal locator processing method of correcting a spatiotemporal locator capable of specifying a trajectory of a representative point of an approximate figure representing an arbitrary region in order to represent a transition of the region over a plurality of frames in video data, obtains the trajectory of the representative point based on the spatiotemporal locator, displays the obtained trajectory of the representative point on a screen, receives input of a correction instruction for the trajectory displayed on the screen, and corrects the spatiotemporal locator based on the correction instruction.
