ABSTRACT:
Methods and integrated systems for camera motion analysis and moving object analysis and methods of extracting semantics mainly from camera motion parameters in videos and video segments without shot changes are described. Typical examples of such videos are a home video taken by a digital camera and a segment, or clip, of a professional video or film. The extracted semantics can be directly used in a number of video/image understanding and management applications, such as annotation, browsing, editing, frame enhancement, key-frame extraction, panorama generation, printing, retrieval, summarization. Automatic methods of detecting and tracking moving objects that do not rely on a priori knowledge of the objects are also described. The methods can be executed in real time.
