Abstract
In an image processing system, a three-dimensional computer model is created of a real-world static background scene. Video images of objects moving on the background are recorded and processed to identify the portions of the image corresponding to the moving objects and to calculate the corresponding positions in the three-dimensional computer model. Each moving object is represented by at least one vertical plane in the three-dimensional computer model. Images, comprising the simulated background and the moving object planes onto which are rendered the video data of the moving object recorded by the video camera, are displayed to the user from any desired viewing direction(s).
