摘要： The invention concerns a method of encoding a current image (le) comprising a step (C2) of determining, in a first image (IR-i) different from the current image, a group of k' pixels corresponding to a current group of k pixels (k'≤k) to be encoded in the current image (l
c ), said encoding method being characterised in that it comprises the following steps: - calculating (C3) a motion vector between each of the k' pixels of the first image (I R-1) and a corresponding pixel of a second image (I R2) different from the current image, after which a field of k' motion vectors is obtained, - predicting (C4) the pixels or the motion of the current group of k pixels in said current image (le) from the obtained field of k' motion vectors.

摘要： Techniques are described for sub-prediction unit (PU) based motion prediction for video coding in HEVC and 3D-HEVC. In one example, the techniques include an advanced temporal motion vector prediction (TMVP) mode to predict sub-PUs of a PU in single layer coding for which motion vector refinement may be allowed. The advanced TMVP mode includes determining motion vectors for the PU in at least two stages to derive motion information for the PU that includes different motion vectors and reference indices for each of the sub-PUs of the PU. In another example, the techniques include storing separate motion information derived for each sub-PU of a current PU predicted using a sub-PU backward view synthesis prediction (BVSP) mode even after motion compensation is performed. The additional motion information stored for the current PU may be used to predict subsequent PUs for which the current PU is a neighboring block.

摘要： A variable length encoder 23 multiplexes hint information into an entire region bitstream, the hint information including motion vector limitation information indicating a maximum range in which a search for a motion vector can be performed, GOP size limitation information indicating a GOP size which is the number of pictures belonging to a GOP, and reference configuration specification information indicating a picture to be referred to at the time of decoding each picture belonging to the GOP. As a result, a bitstream of the entire region which is suitable for efficient generation, with a low operation amount, of a bitstream of a partial region can be generated without causing a reduction in the compression efficiency of the bitstream of the entire region.
