Patent number: 10567776Abstract: Although wedgelet-based partitioning seems to represent a better tradeoff between side information rate on the one hand and achievable variety in partitioning possibilities on the other hand, compared to contour partitioning, the ability to alleviate the constraints of the partitioning to the extent that the partitions have to be wedgelet partitions, enables applying relatively uncomplex statistical analysis onto overlaid spatially sampled texture information in order to derive a good predictor for the bi-segmentation in a depth/disparity map. Thus, in accordance with a first aspect it is exactly the increase of the freedom which alleviates the signaling overhead provided that co-located texture information in form of a picture is present. Another aspect pertains the possibility to save side information rate involved with signaling a respective coding mode supporting irregular partitioning.Type: GrantFiled: June 11, 2019Date of Patent: February 18, 2020Assignee: GE VIDEO COMPRESSION, LLCInventors: Philipp Merkle, Christian Bartnik, Haricharan Lakshman, Detlev Marpe, Karsten Mueller, Thomas Wiegand, Gerhard Tech

Patent number: 10542263Abstract: The way of predicting a current block by assigning constant partition values to the partitions of a bi-partitioning of a block is quite effective, especially in case of coding sample arrays such as depth/disparity maps where the content of these sample arrays is mostly composed of plateaus or simple connected regions of similar value separated from each other by steep edges.

Patent number: 10511834Abstract: A method and apparatus of reference picture list construction for video encoding and decoding includes considering a current picture when an Intra Picture Block Copy (IntraBC) mode is allowed. Embodiments of the reference picture list construction process comprise receiving input data of a current slice in the current picture, determining a temporary reference picture list for the current slice, and determining a final reference picture list from the temporary reference picture list. The reference picture list construction process further comprises adjusting the final reference picture list by setting the current picture to a predefined position in the final reference picture list if the IntraBC mode is allowed. An example of the predefined position is the last position. An example of the reference picture list construction only inserts the current picture into the predefined position when reference picture list modification is not used.Type: GrantFiled: April 29, 2016Date of Patent: December 17, 2019Assignee: HFI Innovation Inc.Inventors: Xiaozhong Xu, Shan Liu

Patent number: 10497090Abstract: Systems, methods, and computer programs are disclosed for reducing memory bandwidth via multiview compression/decompression. One embodiment is a compression method for a multiview rendering in a graphics pipeline. The method comprises receiving a first image and a second image for a multiview rendering. A difference is calculated between the first and second images. The method compresses the first image and the difference between the first and second images. The compressed first image and the compressed difference are stored in a memory. The compressed first image and the compressed difference are decompressed. The second image is generated by comparing the first image to the difference.Type: GrantFiled: May 16, 2017Date of Patent: December 3, 2019Assignee: Qualcomm IncorporatedInventors: Mehrad Tavakoli, Moinul Khan, Mriganka Mondal, Raghavendra Nagaraj

Patent number: 10452963Abstract: A method and system for controlling a home security system. A processor may be trained to recognize an image standard for a scene, wherein the training comprises creating a profile of the image standard. Operational imaging of the scene may be performed to create an operational image. A profile of the operational image may be created. Profiles of the image standard and the operational image may be compared. A state of a security system may be changed as a result of a comparison of the profiles of the image standard and the operational image.Type: GrantFiled: April 17, 2017Date of Patent: October 22, 2019Assignee: GOOGLE LLCInventors: Harry Tannenbaum, Shayan Sayadi

Patent number: 10455231Abstract: A method of MVP (motion vector prediction) for video coding with adaptive motion vector resolution is disclosed. According to the present invention, the MVP coding is applied to the current MV or the current MV is stored depending on the current MV resolution, the reference MV resolution, or both the current MV resolution and the reference MV resolution. In one embodiment, when the current MV resolution corresponds to integer pixel resolution, MVP coding is then applied to the current MV using a modified temporal MV as a motion vector predictor for the current MV, where the modified temporal MV is generated by right-shifting the temporal MV. In another embodiment, when the current MV resolution corresponds to integer pixel resolution, the current MV is left-shifted before it is stored in a memory.Type: GrantFiled: September 30, 2015Date of Patent: October 22, 2019Assignee: HFI INNOVATION INC.Inventors: Xiaozhong Xu, Kai Zhang, Shan Liu, Jicheng An, Xianguo Zhang

Patent number: 10446160Abstract: The present technology relates to a coding device and method, and a decoding device and method, and a program capable of reducing the amount of calculations for decoding. A separating unit separates a supplied bit stream into coded data of channel sources including a dialog source, coded data of additional data sources, and coded data of dialog information. A dialog information decoding unit decodes the coded data of the dialog information. When the dialog information acquired by the decoding is presented to a viewer, the viewer selects one source from the dialog source and some additional dialog sources. An additional dialog source decoding unit decodes only the coded data of an additional dialog source selected by the viewer. An additional dialog selection unit outputs a viewer-selected audio signal from among the audio signals of the dialog source and additional dialog sources in response to the selection instruction of the viewer.Type: GrantFiled: August 31, 2018Date of Patent: October 15, 2019Assignee: Sony CorporationInventors: Toru Chinen, Mitsuyuki Hatanaka, Minoru Tsuji, Hiroyuki Honma

Patent number: 10447990Abstract: A video encoder generates a network abstraction layer (NAL) unit that includes at least a first syntax element and a second syntax element. The first syntax element indicates that the NAL unit belongs to a particular NAL unit type. Coded slices of texture view components and depth view components are encapsulated within NAL units that belong to the particular NAL unit type. The second syntax element indicates whether a NAL unit header of the NAL unit includes an Advanced Video Coding (AVC)-compatible 3-dimensional video (3DV) header extension or includes a Multiview Video Coding (MVC)-compatible 3DV header extension. The video encoder outputs a bitstream that includes the NAL unit. A video decoder receives the NAL unit and determines whether the second syntax element indicates that the NAL unit header of the NAL unit includes the AVC-compatible 3DV header extension or the MVC-compatible 3DV header extension.Type: GrantFiled: February 27, 2013Date of Patent: October 15, 2019Assignee: Qualcomm IncorporatedInventors: Ying Chen, Ye-Kui Wang, Marta Karczewicz
