Patent number: 11983737Abstract: A favorable merging or grouping of simply connected regions into which the array of information samples is sub-divided, is coded with a reduced amount of data. To this end, a predetermined relative locational relationship is defined enabling an identifying, for a predetermined simply connected region, of simply connected regions within the plurality of simply connected regions which have the predetermined relative locational relationship to the predetermined simply connected region. Namely, if the number is zero, a merge indicator for the predetermined simply connected region may be absent within the data stream. In other embodiments, spatial sub-division is performed depending on a first subset of syntax elements, followed by combining spatially neighboring simply connected regions depending on a second subset of syntax elements, to obtain an intermediate sub-division.Type: GrantFiled: November 3, 2022Date of Patent: May 14, 2024Assignee: GE Video Compression, LLCInventors: Philipp Helle, Simon Oudin, Martin Winken, Detlev Marpe, Thomas Wiegand

Publication number: 20240137500Abstract: In accordance with a first aspect, an improved compression efficiency is achieved by letting a block-wise picture codec support a set of intra-prediction modes according to which the intra-prediction signal for a current block of a picture is determined by applying a set of neighboring samples of the current block onto a neural network. A second aspect of the present application is that, additionally or alternatively to the spending of neural network-based intra-prediction modes, the mode selection may be rendered more effective by the usage of a neural network dedicated to determine a rank or a probability value for each of the set of intra-prediction modes by applying a set of neighboring samples thereonto with the rank or probability value being used for the selection of one intra-prediction mode out of the plurality of intra-prediction modes including or coinciding with the set of intra-prediction modes.Type: ApplicationFiled: December 19, 2023Publication date: April 25, 2024Inventors: Jonathan PFAFF, Philipp HELLE, Dominique MANIRY, Thomas WIEGARD, Wojciech SAMEK, Stephan KALTENSTADLER, Heiko SCHWARZ, Detlev MARPE, Mischa SIEKMANN, Martin WINKEN

Publication number: 20240114138Abstract: In transform coefficient coding, predetermined sets of transforms may be used. Embodiments of the present invention provide an encoder and a decoder for encoding a picture into/from a data stream using block-based prediction and block-based residual coding, the encoder and decoder supporting a set of transforms for the block-based residual coding. The encoder and decoder are configured to determine a transform candidate list of transforms for a current residual block out of the set of transforms based on a height and a width of the current residual block, and to encode/decode a prediction residual within the residual block using one selected transform out of the selectable list of transforms and selectively signal/derive the selected transform in/from the data stream.Type: ApplicationFiled: December 6, 2023Publication date: April 4, 2024Inventors: Mischa SIEKMANN, Bjoern STALLENBERGER, Christian BARTNIK, Sebastian BOSSE, Jonathan PFAFF, Philipp HELLE, Jackie MA, Martin WINKEN, Detlev MARPE, Heiko SCHWARZ, Thomas WIEGAND

Publication number: 20230353788Abstract: A previously encoded or reconstructed version of a neighborhood of a predetermined block to be predicted is exploited so as to result into a more efficient predictive coding of the prediction block. In particular, a spectral decomposition of a region composed of this neighborhood and a first version of a predicted filling of the predetermined block results into a first spectrum which is subject to noise reduction and the thus resulting second spectrum may be subject to a spectral composition, thereby resulting in a modified version of this region including a second version of the predicted filling of the predetermined block. Owing to the exploitation of the already processed, i.e. encoded/reconstructed, neighborhood of the predetermined block, the second version of the predicted filling of the predetermined block tends to improve the coding efficiency.Type: ApplicationFiled: June 20, 2023Publication date: November 2, 2023Inventors: Jonathan PFAFF, Martin WINKEN, Christian RUDAT, Heiko SCHWARZ, Thomas WIEGAND, Detlev MARPE

Publication number: 20230345012Abstract: A better rate distortion ratio is achieved by making interrelationships between coding parameters of different planes available for exploitation for the aim of redundancy reduction despite the additional overhead resulting from the need to signal the inter-plane prediction information to the decoder. In particular, the decision to use inter plane prediction or not may be performed for a plurality of planes individually. Additionally or alternatively, the decision may be done on a block basis considering one secondary plane.Type: ApplicationFiled: June 30, 2023Publication date: October 26, 2023Inventors: Martin WINKEN, Heiner KIRCHHOFFER, Heiko SCHWARZ, Detlev MARPE, Thomas WIEGAND

The mode index (200) points to one out of a list (204) of matrix-based intra-prediction modes. The apparatus is configured to predict samples (108) of the predetermined block (18) by computing a matrix-vector product (206) between an input vector (102) derived from reference samples (17) in a neighbourhood of the predetermined block (18) and a prediction matrix (19) associated with the matrix-based intra-prediction mode (k) pointed to by the mode index (200) and associating components (210) of an output vector (208) obtained by the matrix-vector product (206) onto sample positions (104) of the predetermined block. The list (204) of matrix-based intra-prediction modes consists of an even number of matrix-based intra-prediction modes.Type: ApplicationFiled: September 24, 2020Publication date: October 12, 2023Inventors: Jonathan PFAFF, Björn STALLENBERGER, Michael SCHAEFER, Philipp MERKLE, Tobias HINZ, Philipp HELLE, Heiko SCHWARZ, Detlev MARPE, Thomas WIEGAND, Benjamin BROSS, Martin WINKEN, Mischa SIEKMANN

In one example, there is provided a technique to decode or encode a predetermined block of the picture by assigning, based on a first signalization in the data stream, the predetermined block to a first set or a second set; sorting the assigned set of intra-prediction modes according to intra-prediction modes used for neighboring blocks, neighboring the predetermined block, to obtain a list of intra prediction modes; deriving, for the predetermined block, from the data stream, an index into the list of intra prediction modes; and predicting the predetermined block using an intra prediction mode onto which the index points.Type: ApplicationFiled: May 4, 2023Publication date: August 31, 2023Inventors: Jonathan PFAFF, Heiko SCHWARZ, Philipp HELLE, Michael SCHÄFER, Roman RISCHKE, Tobias HINZ, Philipp MERKLE, Björn STALLENBERGER, Martin WINKEN, Mischa SIEKMANN, Detlev MARPE, Thomas WIEGAND
