In an implementation, a supplemental sequence parameter set (“SPS”) structure is provided that has its own network abstraction layer (“NAL”) unit type and allows transmission of layer-dependent parameters for non-base layers in an SVC environment. The supplemental SPS structure also may be used for ...

Li Hua Zhu, Guang Fei Zhu, Jiheng Yang: Spatial diffusion in images. Thomson Licensing, Jack Schwartz and Associates PLLC, June 4, 2013: US08457434 (1 worldwide citation)

The invention is related to spatial diffusion in images. Spatial diffusion helps blurring small discontinuities. Edges become sharper by spatial diffusion as well. A method for generating a spatial diffused image from an input image is described wherein the method comprises applying on the input ima ...

Jiheng Yang, Li Hua Zhu, Hui Zhang: Method and apparatus for partial coefficient decoding and spatial scaling. Thomson Licensing, Jack Schwartz & Associates PLLC, March 1, 2016: US09277210

Video equipment, e.g. for TV producers studios, need to display multiple channels of bit-streams simultaneously. Decoding multiple streams of high bit-rate videos is extremely computational intensive. An improved method for browsing an encoded frequency domain video sequence comprises steps of deter ...

Jiheng Yang, Hui Zhang: Method and apparatus for encoding/decoding image data. Thomson Licensing, Tutunjian & Bitetto P C, May 19, 2015: US09036932

Several attempts have been tried to improve the performance of intra-prediction in video encoding and decoding, which are targeting at pixel level parallelization. A solution for implementing an improved intra-prediction method on a parallel processing platform uses estimated predictors instead of r ...

In video/image coding, macroblocks (MBs) are often intra coded in raster scan order, starting from one seed MB. The invention improves intra prediction for optimized usage of multi-core processors. Encoding starts from multiple intra coded seed MBs per frame, and continues with adjacent MBs. A prede ...
