Real-time video segmentation on a GPU for scene and take indexing

摘要

One embodiment of the present invention sets forth a technique that enables a user to reverse through video content based on scene transitions. By employing a graphics processing unit to compute one or more frame-to-frame correlation coefficients that measure the consistency of sequential images and a central processing unit to analyze the one or more correlation coefficients, a list of scene transitions may be generated in real-time. The list of scene transitions forms the basis for a content-based reverse user control within the playback application. The content-based reverse user control enables a more natural mechanism for reversing through video content, providing the user with a superior overall viewing experience.
