    摘要： The invention relates to a method for generating for at least one macroblock of a high resolution image at least one motion predictor from motion data associated to macroblock(s) of a low resolution image. The method comprises the following steps: —defining a virtual structure made up of non overlapping macroblocks, called virtual base layer macroblocks; —identifying for the high resolution macroblock corresponding virtual base layer macroblocks in the virtual image on the basis of the location of the high resolution macroblock within the high resolution image and on the basis of the ratios of low resolution and high resolution images dimensions; —deriving, for each identified virtual base layer macroblocks, motion data from motion data associated to at least one macroblock of a corresponding low resolution macroblocks pair on the basis of the field/frame mode of the corresponding low resolution macroblocks pair and on the basis of the field/frame mode of the high resolution macroblock; —resampling motion data associated to the corresponding virtual base layer macroblocks so as to generate the at least one motion predictor.

    摘要： The invention relates to a method for deriving motion data for a macroblock divided in elementary blocks of a high resolution picture, called high layer macroblock, from motion data of macroblocks of a low resolution picture, called base layer macroblock. The method comprises the following steps: computing, for each elementary block, an intermediate position within the low resolution picture from the elementary block position depending on the coding modes of the high layer macroblock and of the high and low resolution pictures; identifying the base layer macroblock, called base_MB, comprising the pixel located at the intermediate position; computing a final position within the low resolution picture from the virtual base layer position depending on the coding modes of the base_MB, of the high layer macroblock; identifying the base layer macroblock, called real_base_MB, comprising the pixel located at the final position; and deriving motion data, for the high layer macroblock, from motion data of the identified real_base_MB.

    摘要： The method realizes a motion compensated temporal filtering (MCTF), the temporal filtering being replaced by an intra mode coding to obtain at least one low (L) or high (H) frequency picture if the current picture has a level of correlation with a lower previous picture at a threshold, the low frequency pictures obtained (L) being thus scaled to be adapted, at the energy level, to the pictures obtained by motion compensated temporal filtering, and comprises, at the end of analysis: a selection of the pictures obtained by intra coding of a picture of a low decomposition level with the additional condition, for the high frequency pictures, that this picture is derived itself from an intra coding. a calibration of the picture selected by carrying out at least one reverse step of the scaling step. The applications relate to video compression with temporal prediction.

    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.
