METHOD FOR RECOGNIZING HAND SIGNAL BY SMALL GROUP BASED CLASSIFICATION AND RECORDING MEDIUM RECORDING THE SAME

摘要

PURPOSE: A method for recognizing a hand signal by a small group based classification and a recording medium recording the same are provided to recognize the hand signal according to a hand pose of a user by extracting a characteristic from a queried hand image, classifying the characteristic into a small group, and recognizing the hand pose within the classified small group. CONSTITUTION: If the queried hand image is inputted, the first characteristic value is extracted from the queried hand image. The queried hand image is compared with a representative hand pose model image of each small group. The small group including the queried hand image is recognized by using the first characteristic value and an image comparing result value. The second characteristic value of the queried hand image is extracted. A hand pose model matched with the queried hand image is recognized by comparing the second characteristic value with the hand pose models included in the small group, and the hand signal assigned to the hand pose model is recognized.
