METHOD TO REMOVE OUTLIER FOR RECOGNITION BASED VISUAL TRACKING

摘要

PURPOSE: An outlier removal method for recognition based visual tracking is provided to estimate a posture of an object according to comparison between a tracking point prediction result and a real next frame tracking point. CONSTITUTION: If an extracted feature point of a designated object is grater than predetermined number, the feature point is generated as a tracking point(S120,S130). A tracking thread determines the kind of the tracking point(S140). If the number of stored inlier tracking points is grater than a predetermined number, the tracking thread reflects the inlier tracking point on a posit algorithm(S160,S170). The tracking thread estimates a posture of the object.
