摘要： Methods for determining for high layer macroblocks that use inter-layer prediction, a partitioning of the macroblock. The methods include 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 Partlnfo value; and determining a partitioning of the high layer macroblock in macroblock partitions by comparing between them the Partlnfo values associated with each of the high layer blocks.

摘要： The invention is related to a method for modifying a reference block of a reference image. That is, the method comprises transforming the reference block into a first set of coefficients, modifying the first set of coefficients by help of one or more weights and inverse transforming the modified first set of coefficients wherein said weights are determined by help of one or more further pixels of the current image and by help of one or more further reference pixels of the reference image. 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 of encoding and decoding video images with spatial scalability. The inventive method comprises the following steps consisting in: encoding (5) a low-resolution image, by performing a calculation of a local or reconstructed decoded image, in order to supply an encoded low-resolution image; oversampling (6) the reconstructed image in order to supply a prediction image; and encoding (7) a higher resolution image, comprising a difference calculation with the prediction image in order to supply residues. The invention is characterised in that the method also comprises a step consisting in selecting or calculating filter coefficients to be used for oversampling and a subsequent step consisting in encoding said coefficients such that they can be transmitted to the decoder with the other encoded data. The invention is suitable for hierarchical encoding with spatial scalability.
