IMAGE PROCESSING APPARATUS AND METHOD THEREOF, AND IMAGE PROCESSING PROGRAM

摘要

<P>PROBLEM TO BE SOLVED: To provide an image processing apparatus which is robust and achieves a high-speed tracking, and to provide a method thereof and an image processing program. Ž<P>SOLUTION: The image processing apparatus 100 is provided with: a discrimination part 152 which uses N-pieces of preliminarily generated feature extraction parts 151 to extract N-pieces of feature quantities from an input image and calculates a reliability showing target object likeliness from the N extracted feature quantities; an object detection part 120 which detects the target object included in the input image on the basis of the reliability; a feature selection part 140 which selects M-pieces of feature extraction parts from the N feature extraction parts 151 so that the degree of separation between the reliability of the target object and a reliability of its background is higher than that obtained by using the N-pieces of feature extraction parts 151; and an object tracking part 140 which uses the M-pieces of feature extraction parts selected by the feature selection part 130 to extract M-pieces of feature quantities from the input image and uses the M-pieces of extracted feature quantities to track the target object.
