Patent number: 10587897Abstract: Coding syntaxes in compliance with same or different VDR specifications may be signaled by upstream coding devices such as VDR encoders to downstream coding devices such as VDR decoders in a common vehicle in the form of RPU data units. VDR coding operations and operational parameters may be specified as sequence level, frame level, or partition level syntax elements in a coding syntax. Syntax elements in a coding syntax may be coded directly in one or more current RPU data units under a current RPU ID, predicted from other partitions/segments/ranges previously sent with the same current RPU ID, or predicted from other frame level or sequence level syntax elements previously sent with a previous RPU ID. A downstream device may perform decoding operations on multi-layered input image data based on received coding syntaxes to construct VDR images.Type: GrantFiled: February 16, 2017Date of Patent: March 10, 2020Assignee: Dolby Laboratories Licensing CorporationInventors: Sheng Qu, Peng Yin, Yan Ye, Yuwen He, Walter Gish, Guan-Ming Su, Yufei Yuan, Samir Hulyalkar

Patent number: 10237552Abstract: Inter-color image prediction is based on multi-channel multiple regression (MMR) models. Image prediction is applied to the efficient coding of images and video signals of high dynamic range. MMR models may include first order parameters, second order parameters, and cross-pixel parameters. MMR models using extension parameters incorporating neighbor pixel relations are also presented. Using minimum means-square error criteria, closed form solutions for the prediction parameters are presented for a variety of MMR models.Type: GrantFiled: May 24, 2018Date of Patent: March 19, 2019Assignee: Dolby Laboratories Licensing CorporationInventors: Guan-Ming Su, Sheng Qu, Hubert Koepfer, Yufei Yuan, Samir Hulyalkar

Patent number: 9066070Abstract: In layered VDR coding, inter-layer residuals are quantized by a non-linear quantizer before being coded by a subsequent encoder. Several non-linear quantizers are presented. Such non-linear quantizers may be based on sigmoid-like transfer functions, controlled by one or more free parameters that control their mid-range slope. These functions may also depend on an offset, an output range parameter, and the maximum absolute value of the input data. The quantizer parameters can time-vary and are signaled to a layered decoder. Example non-linear quantizers described herein may be based on the mu-law function, a sigmoid function, and/or a Laplacian distribution.Type: GrantFiled: April 24, 2012Date of Patent: June 23, 2015Assignee: Dolby Laboratories Licensing CorporationInventors: Guan-Ming Su, Yufei Yuan, Sheng Qu

Patent number: 8837825Abstract: Inter-color image prediction is based on color grading modeling. Prediction is applied to the efficient coding of images and video signals of high dynamic range. Prediction models may include a color transformation matrix that models hue and saturation color changes and a non-linear function modeling color correction changes. Under the assumption that the color grading process uses a slope, offset, and power (SOP) operations, an example non linear prediction model is presented.Type: GrantFiled: March 5, 2014Date of Patent: September 16, 2014Assignee: Dolby Laboratories Licensing CorporationInventors: Guan-Ming Su, Sheng Qu, Hubert Koepfer, Yufei Yuan, Samir Hulyalkar, Walter Gish
