<P>PROBLEM TO BE SOLVED: To provide various techniques to support ROI coding for video telephony when extremely low bit rates are required. <P>SOLUTION: The disclosed techniques include a technique for adaptive skipping of a non-ROI area of a video frame to conserve encoding bits for allocation to the ROI. The disclosed techniques also include a technique for allocation of bits to the ROI using weighted bit allocation models at the macroblock (MB) level within the ρ domain. In addition, the disclosed techniques include a technique for generation of a quality metric for ROI video. <P>COPYRIGHT: (C)2013,JPO&INPIT |
