METHOD FOR MOVEMENT TRACKING AND CONTROLLING AVATAR USING WEIGHTED SEARCH WINDOWS

摘要

PURPOSE: Movement tracking and avatar control methods using a weighting detection area are provided to steadily perform tracking without block of a multi-tube seam area. CONSTITUTION: A calculation device sets up two or more regions of interest (ROI) (S520). The calculation device stores the set ROIs in a storage unit. The calculation device extracts feature point values which are pre-set for the ROIs (S530). The calculation device calculates a central point of the feature point values by adding a weighted value to a previous ROI corresponding to the ROIs of a previous frame (S540). The calculation device changes the center of the ROI into the central point of the feature point values (S570).
