APPARATUS AND METHOD FOR TRACKING HUMAN HAND BY USING COLOR FEATURES

摘要

PURPOSE: A hand tracing device and a method use two cameras to steadily and quickly trace a position of a hand, and calculate the actual distance to the hand. CONSTITUTION: A skin color image detector (100) uses a skin color of a predetermined user to detect a skin color image from an image inputted from an image device (10). An image tracking unit (200) uses the detected skin color image to trace the face. A motion image detector (300) uses location information about the traced face to set up ROI (Region of Interest), and detects a movement image in the set ROI. A hand tracking unit (500) traces the position of the hand in candidate areas extracted from a candidate area extractor (400).
