Abstract: A method for manipulating an initial video stream captured by a camera in a video conferencing endpoint into multiple views corresponding to regions of interest. The method comprises detecting objects of one or more predefined types in a frame of the initial video stream; selecting a plurality of crop regions (2200a, 2200b, 2200c) from the frame of the initial video stream, and transmitting the plurality of crop regions. Each crop region includes at least one bounding box and each bounding box includes a detected object of a predefined type.

Abstract: A video processing system, method and computer program storage device cooperate to provide a resource and performance efficient sub-pixel motion search operation. Using on the fly calculations it is possible to provide approximations of sub-pixel positions on one image with respect to another image in an image sequence. A sub-pixel position used to set a motion vector for an encoding process may then be identified with reduced processing and memory resources relative to conventional techniques. Also, by later performing a full encoding cost analysis on the earlier identified sub-pixel position, and keeping track of differences, an interpolation accuracy may be dynamically improved by applying the differences to subsequent image frames.
