Abstract: Apparatus for determining motion in video frames, the apparatus comprising: a feature identifier for matching a feature in succeeding frames of a video sequence, a motion estimator for determining relative motion between said feature in a first one of said video frames and in a second one of said video frames, and a neighboring feature motion assignor, associated with said motion estimator, for assigning a motion estimation to further features neighboring said feature based on said determined relative motion.

Abstract: Apparatus and method for new scene detection in a sequence of video frames, comprising: a frame selector for selecting a current frame and one or more following frames; a down sampler, associated with the frame selector, to down sample the selected frames; a distance evaluator to find a statistical distance between the down sampled frames; and a decision maker for evaluating the statistical distance to determine therefrom whether a scene transition has occurred or not.

Abstract: A system and method for rapid video data compression and transmission for a wireless remote monitor. The compression method is adjusted according to the type of software application which generated the video data, and according to the characteristics of the data itself. Preferably, the type and profile of video data compression is selected by a profile manager, which detects the characteristics of the video data to determine the character of the data, and then which selects the video data compression method and profile according to the video data character. The compression method and system may be used with a device for remotely displaying information from a monitor of a main computer and for remotely and fully controlling the main computer.
