摘要： Certain aspects of a method and system for adaptive temporal interpolation filtering for motion compensation may include computing a plurality of weights for adaptively adjusting one or more parameters of a plurality of linear filters utilized for motion compensation. One or more motion compensated output pictures may be generated based on vector median filtering a plurality of linear filtered output pictures generated by the plurality of linear filters. In instances where two frames are utilized for motion estimation of a video sequence, a motion compensated picture of a previous frame and a motion compensated picture of a current frame may be combined to adaptively compute the subsequent weights. In instances where three or more frames are utilized for motion estimation of a video sequence, the generated one or more motion compensated output pictures may be combined with an extracted desired picture from the video sequence to adaptively compute the subsequent weights.

摘要： A video receiver receives a compressed 3D video comprising a base view video and a residual view video from a video transmitter. The video receiver decodes the received base view video and an enhancement view video of the received compressed 3D video into a left view video and a right view video. Base view pictures are generated selectively based on available memory resource. The residual view video is generated by subtracting base view pictures from corresponding enhancement view pictures. The received base view and residual view videos are buffered for video decoding. Pictures in the buffered residual view video are added to corresponding pictures in the buffered base view video for enhancement view decoding. The left view video and/or the right view video are generated from the resulting decoded base view and enhancement view pictures. A motion vector used for a disparity predicted macroblock is applied to adjacent macroblock pre-fetching.

摘要： Herein described is a system and method that tracks the face of a person engaged in a videophone conversation. In addition to performing facial tracking, the invention provides stabilization of facial images that are transmitted during the videophone conversation. The face is tracked by employing one or more algorithms that correlate videophone captured facial images against a stored facial image. The face may be better identified by way of employing one or more voice recognition algorithms. The one or more voice recognition algorithms may correlate utterances of the person engaged in a conversation to one or more stored utterances. The identified utterances are subsequently mapped to a stored facial image. In a representative embodiment, the system used for performing facial tracking and image stabilization comprises an image sensor, a lens, an actuator, and a controller/processor.

摘要： Aspects of a method and system for hierarchical motion estimation with multi-layer sub-pixel accuracy and motion vector smoothing are presented. Aspects of the system may include hierarchical motion vector computation that enables motion vectors to be computed at each level in the hierarchy based on a distinct pixel resolution level. A smoothing algorithm may be utilized to suppress spurious motion vector generation. The motion vectors computed at one level in the hierarchy may be utilized when computing motion vectors in a subsequent level. A bias value may be computed for each motion vector that provides an evaluation metric that may enable determination of whether the computed motion vector is to be utilized to enable generation of the interpolated image frame.
