摘要： The invention relates to a method for coding a block of pixels comprising the following steps:
- calculate (100) a block of residues from the pixel block and a prediction block,
- transform (104) the block of residues into a block of coefficients with a transform defined by a set of basis functions,
- code (106) the block of coefficients,
The method comprises, before the transformation step (104), a step (102) for rephasing basis functions from residues calculated in a causal neighbourhood of the pixel block. The transformation step uses the rephased basis functions.

摘要： The invention is related to a method for modifying a reference block (RFBL) of a reference image (I_REF).
That is, the method comprises transforming (TRF) the reference block (RFBL) into a first set (REF(u,v,)) of coefficients, modifying the first set (REF(u,v,)) of coefficients by help of one or more weights (TR(u,v,)) and inverse transforming (ITR) the modified first set of coefficients wherein said weights (TR(u,v,)) are determined by help of one or more further pixels of the current image (I_CUR) and by help of one or more further reference pixels of the reference image (I_REF).
Using further pixels of the current image as well as further reference pixels of the reference image allows spectral weights to be determined such that they reflect fading effects. Especially, if a reference frame consists of two cross-faded frames of which one shall be predicted by help of said reference frame, then, spectral domain weighting allows for separating the relevant of the two frames.

摘要： The invention relates to a method for coding a block of pixels comprising the following steps:
- determine (10) a prediction block for the pixel block from a motion vector;
- calculate (12) a residue between the pixel block and the prediction block; and

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.
