摘要： A method for constructing a gesture mouse utilizes an object e.g., a user's palm) in the background of the photographed region of a video camera as a determination basis. In a computer system, (1) for the image of an object, the point with maximum Y-axis value is set to be a cursor; (2) the point with maximum X-axis value is set to be a push button; (3) the cursor and the push button are used as centers to set small tracking areas respectively; (4) if the distance between the cursor and the push button becomes greater than a designated threshold within a time period, an action of the push button is determined to occur. Images obtained by the video camera are input into a computer through the digital image interface of the video camera or an analog/digital converting card for further processing.

摘要： A facial animation production method for producing 3-dimensional (3D) facial animation data in response to input video data includes the following steps. First, data positioning and character sorting processes are performed on the input video data to acquire first-layer character data, for indicating multiple first-layer character points, and first-layer model data. Next, first-layer model outline data and first-layer character outline data are respectively obtained according to the first-layer model data and the first-layer character data. Then, the first-layer character outline data is compared with the first-layer model outline data to judge whether a judgment condition is satisfied. If not, output character data are produced according to the first-layer character data, and fundamental facial-mesh transformation data are thus produced. Thereafter, the 3D facial animation data are displayed according to the fundamental facial-mesh transformation data.
