OBJECT TRAJECTORY IDENTIFICATION DEVICE, OBJECT TRAJECTORY IDENTIFICATION METHOD, AND OBJECT TRAJECTORY IDENTIFICATION PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide an object trajectory identification device, its identification method and an identification program for highly accurately identifying a trajectory of an object.;SOLUTION: The object trajectory identification device identifies a trajectory of a first object moving together with a time included in a video to be input. The device includes: a trajectory feature value extracting means for extracting the first object in a time series image comprising the video to generate trajectory data of the object and extracting the trajectory feature value of the object from the generated trajectory data; a motion feature value extracting means for extracting a second object moving in accordance with the trajectory of the first object and extracting a motion vector of the extracted second object as a feature value; a character feature value extracting means for extracting character information included in the video as a feature value; and an identification means for identifying the trajectory of the first object from among a preset trajectory kind on the basis of respective feature quantities obtained by the trajectory feature value extracting means, the motion feature value extracting means and the character feature value extracting means.;COPYRIGHT: (C)2009,JPO&INPIT
