    • The edge identification system receives a pair of images from which an in-between image is to be created. The edge identification system calculates two vector fields: one to warp the second image onto the first, and the other to warp the first image onto the second. The two vector fields are typically symmetric; however, the fields are not symmetric along the edge of an object (e.g., the foreground) that is moving differently than the layer behind it (e.g., the background). This type of movement creates occlusions in which an object that was visible in one image will not be visible in the other image and vice versa. The edge identification system uses these areas to automatically identify the edges of moving objects. Thus, the edge identification system can identify the edges of objects without requiring the user to provide a matte or other manual assistance.
    • 边缘识别系统接收将要创建中间图像的一对图像。 边缘识别系统计算两个矢量场:一个用于将第二图像扭曲到第一图像上,另一个将第一图像扭曲到第二图像上。 两个矢量场通常是对称的; 然而,沿着与其背后的层(例如,背景)不同的物体(例如,前景)的边缘,这些场不是对称的。 这种类型的移动会产生遮挡,其中在一个图像中可见的对象在另一个图像中将不可见,反之亦然。 边缘识别系统使用这些区域来自动识别移动物体的边缘。 因此,边缘识别系统可以识别对象的边缘,而不需要用户提供哑光或其他手动辅助。
