Patent number: 11812021Abstract: Quantization matrix can be used to adjust quantization of transform coefficients at different frequencies. In one embodiment, a single fixed parametric model, such as a polynomial is used to represent a quantization matrix. Modulation of bit cost and complexity is achieved by specifying only the n first polynomial coefficients, the remaining ones being implicitly set to zero or other default values. One form of the single fixed polynomial is a fully developed polynomial in (x,y), where x,y indicate the coordinates of a given coefficient in a quantization matrix, with terms ordered by increasing exponent. Since higher exponents are the last ones, reducing the number of polynomial coefficients reduces the degree of the polynomial, hence its complexity. The polynomial coefficients can be symmetrical in x and y, and thus reducing the number of polynomial coefficients that need to be signaled in the bitstream.Type: GrantFiled: August 18, 2022Date of Patent: November 7, 2023Assignee: InterDigital CE Patent Holdings, SASInventors: Philippe De Lagrange, Ya Chen, Edouard Francois

Patent number: 11805387Abstract: In order to perform location-specific services of a broadcasting unit, virtual cells for the location-specific services are set up so that cell data, which define a local cell area, are transmitted to a mobile receiving device via the broadcasting unit. The cell data are stored in the mobile receiving device. The mobile receiving device establishes its current position and determines whether it is located in the cell area. In the event the mobile receiving device is located in the cell area, the receiving device performs a service assigned to the cell data. The setting up of cells for local-specific services by the broadcasting unit in a multitude of mobile receiving devices in the service area of the broadcasting unit enables geographical areas inside and outside the service area to be slit up into smaller, interactive and virtual service cells and cell clusters in a dynamic and optimal manner according to need and geographical and/or service-specific parameter.Type: GrantFiled: September 21, 2021Date of Patent: October 31, 2023Assignee: InterDigital CE Patent Holdings, SASInventor: Rudolf Ritter

Patent number: 11758187Abstract: A sequence of point clouds is encoded as a video by an encoder and transmitted to a decoder which retrieves the sequence of point clouds. Visible points of a point cloud are iteratively projected on projection maps according to at least two centers of projection, to determine a patch data item lists. One of the centers of projection is selected and corresponding image patches are generated and packed into a picture. Pictures and associated patch data item list are encoded in a stream. The decoding method decodes pictures and associated patch data item lists. Pixels of image patches comprised in pictures are un-projected according to data stored in associated patches. The methods have the advantage of encoding every point of point clouds in a manner avoiding artifacts and allowing decoding at video frame rate.Type: GrantFiled: September 1, 2021Date of Patent: September 12, 2023Assignee: InterDigital CE Patent Holdings, SASInventors: Julien Fleureau, Thierry Tapie, Franck Thudor

Patent number: 11694349Abstract: The present invention generally relates to an apparatus and a method for obtaining a registration error map representing a level of sharpness of an image. Many methods are known which allow determining the position of a camera with respect to an object, based on the knowledge of a 3D model of the object and the intrinsic parameters of the camera. However, regardless of the visual servoing technique used, there is no control in the image space and the object may get out of the camera field of view during servoing. It is proposed to obtain a registration error map relating to an image of the object of interest generated by computing an intersection of a re-focusing surface obtained from a 3D model of said object of interest and a focal stack based on acquired four-dimensional light-field data relating to said object of interest.Type: GrantFiled: September 22, 2020Date of Patent: July 4, 2023Assignee: INTERDIGITAL CE PATENT HOLDINGSInventors: Julien Fleureau, Pierre Hellier, Benoit Vandame
