GESTURE RECOGNIZING SYSTEM AND METHOD BY ANALYZING TRACE ON POLAR COORDINATES

摘要

PURPOSE: A gesture recognizing system and method in accordance with the trace analysis on polar coordinates is provided to pursue the motion of hand by using the natural color information included in the hand and to recognize the obtained information as the dynamic pattern. CONSTITUTION: A gesture recognizing system and method in accordance with the trace analysis on polar coordinates comprises a hand region extractor(11), a key-gesture spotter(12) and a gesture recognizer(13). The hand region extractor(11) separates the hand region from the video image inputted continuously and extracts the dynamic gesture. The key-gesture spotter(12) separates the key-gesture which is the meaning gesture from the dynamic gesture. The gesture recognizer(13) extracts the command is meant by the key-gesture. A gesture identification method in accordance with the track analysis on polar coordinates comprises the steps of;inputting the hand motion gesture image which means the specific command;separating the hand region from the hand motion gesture image and obtaining a track of gesture;separating the key-gesture which is the meaning gesture from the track of gesture;and extracting the command is meant by the key-gesture.
