In one example, an apparatus for coding video data comprises a video coder configured to, for a parallel motion estimation (pme) region comprising a plurality of blocks of video data within the pme region, identify a common set of spatial candidate blocks outside of and adjacent to the pme region, each of the common set of spatial candidate blocks at a respective, predefined location relative to the pme region and, for each of the blocks within the pme region for which motion information prediction is performed, generate a respective motion information candidate list, wherein, for at least some of the blocks within the pme region for which motion information prediction is performed, generating the motion information candidate list comprises evaluating motion information of at least one of the common set of spatial candidate blocks for inclusion in the motion information candidate list for the block.. .

Dominant motion estimation for image sequence processing
Herein is described a method of estimating dominant motion between a current frame n and another frame m of an image sequence having a plurality of frames, the method comprising generating integral projections of the images and using gradients of those projections and using differences between the projections. The input may be any sequence of image frames from an image source, such as a video camera, an ir or x-ray imagery, radar, or from a storage medium such as computer disk memory, video tape or a computer graphics generator..

Method and device for correlation channel estimation
A hash-based distributed video coding architecture has an encoder with an input video sequence organized in groups of pictures (gops) decomposed into key frames using h264/avc intra frame coding. The wyner-ziv (wz) frames are encoded in two parts, a hash layer and a wz layer.
