Publication number: 20250014228Abstract: In one implementation, we improve the binary voxel-based octree coding method, via a proposed state summarization module for context modeling. Given a current voxel to be encoded or decoded, instead of directly estimating its occupancy probability based on the associated binary occupancy context, a proposed state summarization module is applied to convert the original binary context to a summarized representation. Under the summarized representation, the estimation of the occupancy probability becomes more affordable and effective. In particular, density-based state summarization, pattern-based, learning-based state summarization, and learning-based state summarization methods are provided.Type: ApplicationFiled: October 18, 2022Publication date: January 9, 2025Inventors: Maurice QUACH, Jiahao PANG, Muhammad Asad LODHI, Dong TIAN, Giuseppe VALENZISE, Frederic DUFAUX

Publication number: 20250005764Abstract: Points are grouped from a point cloud using Concavity-induced Distance (CID). First, a set of seed points is sampled from the input point cloud. Then a grouping of points is conducted based on a nearest neighbor search computed using CID. These two steps enable two novel solutions in point cloud segmentation and scene abstraction. In one embodiment, CID is determined between two points residing within an object surface. In a second embodiment, a CID is determined between groups of points.Type: ApplicationFiled: November 11, 2022Publication date: January 2, 2025Inventors: Ruoyu WANG, Chen FENG, Dong Tian

Publication number: 20240406427Abstract: Methods and apparatuses for decoding and encoding point cloud data are described herein. A method may include accessing point cloud data compressed based on a tree structure. The method may further comprise fetching points in a neighborhood associated with a current node of the tree structure, and computing a feature using a point-based neural network module, based on three-dimensional (3D) locations of the fetched points. The method may include predicting, using a neural network module, an occupancy symbol distribution for the current node based on the feature, and determining the occupancy for the current node from the encoded bitstream and the predicted occupancy symbol distribution. The method may include computing another feature using a convolution-based neural network module, based on a voxelized version of the fetched points, and fusing the feature and the another feature with one or more known features of a current node to compose a comprehensive feature.Type: ApplicationFiled: October 5, 2022Publication date: December 5, 2024Applicant: INTERDIGITAL VC HOLDINGS, INC.Inventors: Muhammad Asad Lodhi, Jiahao Pang, Dong Tian

Patent number: 12120326Abstract: Several implementations relate to 3D video formats. One or more implementations provide adaptations to MVC and SVC to allow 3D video formats to be used. According to a general aspect, a set of images including video and depth is encoded. The set of images is related according to a particular 3D video format, and are encoded in a manner that exploits redundancy between the set of images. The encoded images are arranged in a bitstream in a particular order, based on the particular 3D video format that relates to the images. The particular order is indicated in the bitstream using signaling information. According to another general aspect, a bitstream is accessed that includes the encoded set of images. The signaling information is also accessed. The set of images is decoded using the signaling information.Type: GrantFiled: February 19, 2010Date of Patent: October 15, 2024Assignee: INTERDIGITAL MADISON PATENT HOLDINGSInventors: Dong Tian, Po-Lin Lai, Jiancong Luo

Publication number: 20240305858Abstract: A media player providing real time rewind playback of a played media file having segments of frames. A last segment N of the played media file is cached and rendered on a device, such as a mobile device, then a previous segment N?1 is cached and rendered, and the process continues until there are no more segments of the played media file to cache and render. Only a segment of the played media file is cached at a time, rather than the whole media file, such that the played media file can be replayed on the fly.Type: ApplicationFiled: March 8, 2023Publication date: September 12, 2024Inventors: Dong Tian, Guanshu Chen

Publication number: 20240282013Abstract: In one implementation, we propose the UnfoldingOperator, which unfolds/flattens an unorganized input 3D point cloud onto a regular 2D grid. Given an input point cloud, an input 2D grid and the reconstructed point cloud produced by the FoldingNet, our proposal maps the input point cloud onto the 2D grid based on the reconstructed point cloud, leading to a 3-channel image. Alternatively, instead of using an image alone to represent a point cloud, the point cloud is decomposed into a codeword and a 3-channel residual image. This residual image is obtained by subtracting the reconstructed point cloud from the original input. The proposed UnfoldingOperator can be applied to point cloud compression, leading to a corresponding compression system that we call UnfoldingCompression. The UnfoldingCompression can work with the TearingCompression, where we can adaptively choose whether to use the UnfoldingCompression or TearingCompression.Type: ApplicationFiled: June 20, 2022Publication date: August 22, 2024Inventors: Jiahao PANG, Dong TIAN, Maurice QUACH, Giuseppe VALENZISE, Frederic DUFAUX

Publication number: 20240193819Abstract: In one implementation, a learnable transformation TearingTransform over 3D point cloud data is proposed. The TearingTransform could decompose point clouds into two channels: a low rank channel and a sparse channel. The low rank channel corresponds to a codeword representing a rough shape of a point cloud. The sparse channel appears as an image-like data representing residual information that can refine the reconstructed point locations. In an encoder based on TearingTransform, a PN module is used to generate the codeword from the input point cloud; a FN module is used to reconstruct a preliminary point cloud from the codeword and an initial grid image; and a TN module modifies the initial grid image to generate an adjusted grid image. The codeword and the adjusted grid image are compressed. At the decoder, the point cloud can be reconstructed based on the decompressed codeword and adjusted grid image.Type: ApplicationFiled: April 29, 2022Publication date: June 13, 2024Inventors: Dong TIAN, Jiahao PANG, Maurice QUACH, Giuseppe VALENZISE, Frederic DUFAUX
