IPC: G06T1/00
Filed: 2002-05-28
Abstract: <P>PROBLEM TO BE SOLVED: To provide a system capable of inputting an instruction or the like by recognizing the shape of a hand.   <P>SOLUTION: Two kinds of hand shape recognition images, namely, a hand region extraction image (S204) and a hand region narrow line image (S206), are formed from an input image (S202) by a camera or the like. An apparent characteristic of the hand such as thickness of a finger is extracted from the hand region extraction image as an image characteristic, and a skeletal characteristic of the hand such as a direction of the hand or a root coordinate of the finger is extracted similarly from the hand region narrow line image. First of all, the number of fingers is recognized (S208), and when the number is 0.5 or more, the direction of the hand is determined (S210) by using the acquired image characteristic and a structural characteristic of the hand, and the finger region is extracted (S212). Then, the image characteristic is acquired (S214) by analyzing the acquired finger region extraction image and the hand shape recognition image, and it is recognized which finger is stretched (S216). Thirty- two kinds of hand shapes can be recognized in this way.  <P>COPYRIGHT: (C)2004,JPO
