摘要： The invention relates to a method of measuring blocking artefacts on the basis of video data encoded in accordance with a block encoding technique. This method comprises a step of computing a monodimensional inverse discrete transform (31) of a first row of a first block of encoded video data, suitable for supplying a value of a first virtual border pixel (vep1). It also comprises a step of computing a monodimensional inverse discrete transform (32) of a first row of a second block of encoded video data, the second block being adjacent to the first block, suitable for supplying a value of a second virtual border pixel (vep2). Finally, the method comprises a step of computing (33) a blocking artefact level (VEP-L) on the basis of an absolute value of the difference betwe en the values of the first and second virtual pixels. This method finds its application, for example, in video encoders, decoders and transcoders.

摘要： Three-dimensional (3D) subband coding schemes use motion compensation in their temporal filtering stage. Unfortunately, this procedure introduces two drawbacks : (a) the MC being applied at the full resolution, a drift appears when decoding at a lower resolution, and (b) all the motion vectors estimated at full resolution are transmitted, which is a waste of bits. According to the invention, a low resolution sequence is first obtained by generating from the original input sequence of frames - by means of a wavelet decomposition - a sequence of low resolution frames and performing on them a motion compensated spatio-temporal analysis. Then, a motion compensated spatio-temporal analysis of each full resolution group of frames is performed, and the low frequency subbands of the decomposition are finally replaced, at each temporal decomposition level, by the corresponding spatio-temporal subbands of the generated low resolution sequence. The modified sequence thus obtained is finally coded. Thanks to this approach, a good behavior at low resolution is maintained (no more drift) while getting closer to the performance of a classic 3D subband codec at full resolution.

摘要： The invention relates to a video decoding method for the decompression of an input coded bitstream corresponding to an original video sequence. The sequence has been divided into successive groups of frames (GOFs) and coded by means of a three-dimensional subband video coding method. According to the invention, the decoding method is iterative and comprises as many iterations as the number of couples of frames in each GOF, each iteration itself including, for the reconstruction of each successive couple of frames of each GOF, the sub-steps of decoding the coded bitstream that corresponds to the current GOF, storing, from the decoded bitstream thus obtained, only the data related to the current couple of frames and appropriate subbands containing some information on at least one frame of said current couple of frames, and, from said related data and said appropriate subbands, synthesizing the two frames of said current couple of frames.

摘要： A coding device (Dl), for an electronic equipment, comprises coding means (CM) for encoding movie data into a compressed scalable bitstream (SVB), starting from at least one interlaced base layer (BL) comprising interlaced fields, amongst which some are duplicated fields associated to a field repeat flag, and at least one progressive enhancement layer (EL) comprising progressive frames. These coding means are more precisely arranged i) to constitute a prediction layer (PL) comprising prediction frames defined from first and second fields of the interlaced base layer (BL), except those containing a duplicated field, and ii) to encode the progressive frames of each progressive enhancement layer (EL) by computing the difference between each prediction frame and the corresponding progressive frame, while taking into account the field repeat flags associated to the corresponding duplicated fields of the interlaced base layer (BL), in order to handle the missing prediction frames.
