  • Patent number: 12230001
    Abstract: There is disclosed an encoder, a decoder, related methods, and non-transitory storage units storing instructions which, when executed by a computer, cause the computer to perform the methods. At an encoder (300), after a spatial transformation stage (304), there is obtained a spatially transformed version (306) of input image information (302) having multiple bands and, for each band, multiple transform band coefficients. After the generation of precincts (311), each comprising transform coefficients covering a predetermined spatial area of the input image information (302), there is provided a component transformation stage (320, 325), to apply one component transformation (CTr) selected (327) out of a plurality of predetermined component transformations, to each band (102?) of each precinct (311). Hence, there is obtained a spatially transformed and color transformed version (323) of the input image information (302), which is subsequently quantized and entropy encoded.

  • Patent number: 12149744
    Abstract: An apparatus for decoding a sequence of pictures from a data stream is configured for decoding a picture of the sequence by deriving a residual transform signal of the picture from the data stream; combining a residual transform signal with a buffered transform signal approximation of a previous picture of the sequence so as to obtain a transform signal representing the picture, the transform signal having a plurality of transform coefficients; and subjecting the transform signal to a spectral-to-spatial transformation. The apparatus is configured for deriving the buffered transform signal approximation from a further transform signal representing the previous picture so that the buffered transform signal approximation has approximations of further transform coefficients of the further transform signal.

  • Patent number: 11546614
    Abstract: There are disclosed techniques for encoding and/or decoding multiple image information, e.g. through recurrent neural network based stereo compression. In an image encoder (1), a primary block (100) encodes a primary image information, and a secondary block (300) encodes a secondary image information. States for the primary block are transformed onto states for the secondary block at a transformation block (200), which keeps into account correspondence information (e.g. disparity information) between the first image information and the second image information. In an image decoder (1b), a primary block (100) decodes an encoded version of a primary image information, and a secondary block (300) encodes an encoded version of a secondary image information. States for the primary block are transformed onto states for the secondary block at a transformation block (200), which keeps into account correspondence information (e.g.

  • Patent number: 11457232
    Abstract: A coding efficiency improvement is achieved by performing bit-plane coding in a manner so that coefficient groups for which the set of coded bit-planes is predictively signaled in the datastream, are grouped in two group sets and if a signal is spent in the datastream which signals, for a group set, whether the set of coded bit-planes of all coefficient groups of the respective group set are empty, i.e. all coefficients within the respective group sets are insignificant. In accordance with another aspect, a coding efficiency improvement is achieved by providing bit-plane coding with group-set-wise insignificant signalization according to the first aspect as a coding option alternative relative to the signalization for group sets for which it is signaled that there is no coded prediction residual for the coded bit-planes for the claim groups within the respective group set.

  • Patent number: 10956644
    Abstract: A method for adding an electrical interconnection within a three-dimensional integrated circuit (3-D IC) is disclosed. The method may include creating, within a design file of a 3-D IC that specifies a layout for a first chip of the 3-D IC, design data corresponding to a set of through-silicon via (TSV) reservation areas. The method may also include receiving an engineering change order (ECO) and releasing, in response to the ECO, at least one TSV reservation area for reuse. The method may also include adding, by re-using at least one TSV reservation area, an electrical interconnection within the design file of the first chip of the 3-D IC.
