Abstract
A method for indexing video sequences relative to a reference model. A system implementing the method includes an (optional) image pre-processor that produces the reference model or is provided the reference model. The pre-processor is then provided input image data such as a video sequence containing a series of frames of a particular scene. The pre-processor performs a transformation to align the images within the video sequence with the reference model. The pre-processor then stores the transformation, the reference model and the image data within a mass storage device such as a hard disk drive. Subsequently, the system provides access to the information stored within the mass storage device through a user interface. The user may recall and position on a computer screen the reference model, select a particular point within the reference model, and request that the system produce all of the image data that contains that particular point within the reference model.
