    • A gesture recognition system includes an image pick-up device, a processor, an operation engine, an optimal template selection means, and a display terminal. The image pick-up device is for capturing an image containing a natural gesture. The processor is for finding out a skin edge of a skin part from the image, and then classifying the skin edge into multiple edge parts at different angles. The operation engine has multiple parallel operation units and multiple gesture template libraries of different angle classes. These parallel operation units respectively find out gesture templates most resembling the edge parts in the gesture template libraries of different angle classes. The optimal template selection means selects an optimal gesture template from the resembling gesture templates found out by the parallel operation units. The display terminal is for displaying an image of the optimal gesture template. Thereby, marker-less and real-time gesture recognition is achieved.
    • 手势识别系统包括图像拾取装置,处理器,操作引擎,最佳模板选择装置和显示终端。 图像拾取装置用于捕获包含自然手势的图像。 处理器用于从图像中发现皮肤部分的皮肤边缘,然后将皮肤边缘分成不同角度的多个边缘部分。 操作引擎具有多个并行操作单元和多个不同角度类的多个手势模板库。 这些并行操作单元分别找出最类似于不同角度类的手势模板库中的边缘部分的手势模板。 最佳模板选择装置从由并行操作单元发现的类似手势模板中选择最佳手势模板。 显示终端用于显示最佳手势模板的图像。 从而实现无标记和实时手势识别。

    • A collision simulation method of a three dimensional (3D) object is provided, wherein the 3D object is composed of a plurality of polygonal meshes. First, a collision between the polygonal meshes and an object is detected. When one of the polygonal meshes is collided by the object, at least one virtual vertex is generated at a first position where the polygonal mesh is collided by the object, wherein the polygonal mesh includes a plurality of vertexes. Then, the virtual vertex is connected to the vertexes to form a plurality of sub meshes. Next, a force between the object and the virtual vertex is calculated to update the first position of the virtual vertex into a second position. After that, forces between the virtual vertex and the vertexes are calculated according to the second position of the virtual vertex so as to update the positions of the vertexes.
    • 提供了三维(3D)对象的碰撞模拟方法,其中3D对象由多个多边形网格组成。 首先,检测多边形网格和对象之间的碰撞。 当所述多边形网格中的一个被所述对象冲突时,在所述多边形网格与所述对象相冲突的第一位置处生成至少一个虚拟顶点,其中所述多边形网格包括多个顶点。 然后,虚拟顶点连接到顶点以形成多个子网格。 接下来,计算对象和虚拟顶点之间的力,以将虚拟顶点的第一位置更新为第二位置。 之后,根据虚拟顶点的第二位置计算虚拟顶点和顶点之间的力,以便更新顶点的位置。
