Publication number: 20210034696Abstract: The systems and methods discussed herein implement a volumetric approach to point cloud representation, compression, decompression, communication, or any suitable combination thereof. The volumetric approach can be used for both geometry and attribute compression and decompression, and both geometry and attributes can be represented by volumetric functions. To create a compressed representation of the geometry or attributes of a point cloud, a suitable set of volumetric functions are transformed, quantized, and entropy-coded. When decoded, the volumetric functions are sufficient to reconstruct the corresponding geometry or attributes of the point cloud.Type: ApplicationFiled: October 21, 2020Publication date: February 4, 2021Inventors: Philip A. Chou, Maxim Koroteev, Maja Krivokuca, Robert James William Higgs, Charles Loop

Patent number: 8200035Abstract: Provided are a method and apparatus for correcting quantized coefficients. In the method, statistical values of coefficients and quantized coefficients are extracted from a received video data stream, coefficient correction values for each pixel position in blocks are determined by using the statistical distribution of the coefficients depending on the statistical values, and then the coefficients are corrected by respectively adding the coefficient correction values to corresponding coefficients of respective pixel positions.Type: GrantFiled: July 15, 2008Date of Patent: June 12, 2012Assignee: Samsung Electronics Co., Ltd.Inventors: Maxim Koroteev, Alexander Alshin, Elena Alshina, Vadim Seregin, Ekaterina Nesterova
