摘要： The invention relates to a method for determining for a high layer macroblock that uses inter-layer prediction a partitioning of the macroblock in partitions. It comprises the following steps: —dividing the high layer macroblock in non-overlapping high layer blocks of a predefined size; —determining a corresponding base layer pixel for one pixel, called reference pixel, of each high layer block; —identifying, for each reference pixel, a base layer macroblock to which the corresponding base layer pixel belongs, a base layer partition to which the corresponding base layer pixel belongs in the identified base layer macroblock, a base layer sub-partition to which the corresponding base layer pixel belongs in the identified base layer partition if the sub-partition exists; —deriving, for each of the high layer block, a single value, called Part Info value; and —determining a partitioning of the high layer macroblock in macroblock partitions by comparing between them the Part Info values associated with each of the high layer blocks.

摘要： The process for coding the current block comprises a step of selecting the predicted block from among candidate blocks, the selection being dependent on a difference DBdrx,dry between the co-located block of the current image block lying in an image of type B and the block of a reference image, the latter block being designated by the motion vector with components drx, dry which is allocated to co-located block and which is colinear with the motion vector Vp allocated to the current block and designating the candidate block. Applications relate to data compression, the transmission of digital images using the video coding standard comprising a direct prediction mode, for example the h263, MPEG4 or h261 standard.

摘要： The invention is related to a method for determining a filter for interpolating one or more pixels comprised in a frame. The proposed method comprises the step of determining the filter based on other pixels in the remainder of the frame wherein a motion vector associated with said pixels has at least one motion parameter in common with another motion vector associated with said other pixels and the filter is determined such that a quality of an interpolation of said other pixels, said interpolation being determined by help of said determined filter, reaches or exceeds the quality of any other interpolation of said other pixels determinable by help of one of different filter candidates comprised in a filter candidate set. In determining the filter solely on different other pixels of the same frame, said method for determining a filter for interpolation allows for realization of a single pass encoding framework.
