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

Patent number: 11856219Abstract: A proposed intermediate way of handling the renderable portion of the first view results in more efficient coding. Instead of omitting the coding of the renderable portion completely, even more efficient coding of multi-view signals entails merely suppressing the coding of the residual signal within the renderable portion, whereas the prediction parameter coding still takes place from the non-renderable portion of the multi-view signal across the renderable portion so that prediction parameters for the renderable portion may be exploited for predicting parameters for the non-renderable portion. The additional coding rate for transmitting the prediction parameters for the renderable portion may be kept low as this merely aims at forming a continuation of the parameter history across the renderable portion to serve as a basis for prediction parameters of other portions of the multi-view signal.Type: GrantFiled: July 12, 2022Date of Patent: December 26, 2023Assignee: GE Video Compression, LLCInventors: Sebastian Bosse, Heiko Schwarz, Thomas Wiegand, Tobias Hinz

Publication number: 20230328271Abstract: Rendered portions of a renderable portion of a first view of a multi-view signal are introduced into a prediction loop of a multi-view encoder to form a reference signal for the block-based prediction of the encoder's view predictor may improve the prediction and thereby increasing the coding efficiency. The introduction may be performed by completely inserting the renderable portion into the prediction loop to form new reference pictures with their own reference picture indices in addition to reference pictures obtained by the reconstructed version of the multi-view signal of the block-based prediction. Alternatively, the rendered portion may be introduced into the prediction loop completely, but with replacing the normal prediction reference signal, i.e., the normally reconstructed signal as obtained by block-based prediction. Alternatively, it may be signaled within the data stream which portions of the renderable portion are used to replace respective portions in the normally reconstructed signal.Type: ApplicationFiled: June 8, 2023Publication date: October 12, 2023Inventors: Sebastian BOSSE, Heiko SCHWARZ, Thomas WIEGAND, Heribert BRUST

Patent number: 11363268Abstract: Coding quantization parameter variation or adaptation is made more effective by basing the determination of a coding quantization parameter for a predetermined block of the picture on a dispersion of a statistical sample value distribution of a high-pass filtered version of the predetermined block. The usage of the high-pass filtered version of the predetermined block as a basis for the determination of the dispersion instead of using, for instance, the un-filtered or original version of the predetermined block assists in a better adaptation of the resulting coding quantization parameter variation across the picture to the human visual system. Alternatively or additionally, coding quantization parameter variation or adaptation across a picture is made more efficient by a control of coding quantization parameter variation/adaptation across a picture in a manner dependent on a prediction of the actual dispersion.Type: GrantFiled: March 20, 2020Date of Patent: June 14, 2022Assignee: Fraunhofer-Gesellschaft zur Förderung der angewandten Forschung e.V.Inventors: Christian Helmrich, Thomas Wiegand, Adam Wieckowski, Heiko Schwarz, Detlev Marpe, Sebastian Bosse, Benjamin Bross
