A method of view selection in a teleconferencing environment includes receiving a frame of image data from an optical sensor such as a camera, detecting one or more conference participants within the frame of image data, and identifying an interest region for each of the conference participants. Identifying the interest region comprises estimating head poses of participants to determine where a majority of the participants are looking and determining if there is an object in that area. If a suitable object is in the area at which the participants are looking, such as a whiteboard or another person, the image data corresponding to the object will be displayed on a display device or sent to a remote teleconference endpoint.

A video processing apparatus and methodology are implemented as a combination of a processor and a video decoding hardware block to decode video data by performing piecewise processing of overlap smoothing and in-loop deblocking in a macroblock-based fashion. With this approach, a smaller on-board memory may be used for the in-loop filtering operations of the video decoding hardware block. By pipelining the piecewise processing operations, latency in the filtering operations is hidden and the filtering output is smoothed, thereby avoiding the need for bursts of fetching and storing of blocks.

Piecewise processing of overlap smoothing and in-loop deblocking

A video processing apparatus and methodology are implemented as a combination of a processor and a video decoding hardware block to decode video data by providing the video decoding block with an in-loop filter and a scratch pad memory, so that the in-loop filter may efficiently perform piecewise processing of overlap smoothing and in-loop deblocking in a macroblock-based fashion which is a much more efficient algorithm than the frame-based method.
