Title: Innovations in Video Coding by Liwei Guo
Introduction
Liwei Guo is a prominent inventor based in Hong Kong, CN. He has made significant contributions to the field of video coding, holding 2 patents that showcase his innovative approaches to digital video processing.
Latest Patents
Guo's latest patents include "Decoding with embedded denoising" and "Optimal denoising for video coding." The first patent focuses on methods and systems for denoising embedded digital video decoding. It involves obtaining the prediction and residue block of a current frame from the motion vector. The variance of the residue block is calculated using prior reference blocks, and a causal temporal linear minimum square error estimator is employed to calculate a filter coefficient. The residue block is then modified using this filter coefficient, resulting in an output digital bitstream of blocks of pixels for the current frame, utilizing the modified residue block and prior denoised prediction values from previous frames. The second patent presents an optimal denoising method for video coding that utilizes very few pixels and linear operations. This method can be seamlessly integrated into the motion compensation process of video encoders. It is designed to be simple and flexible while delivering high performance and producing visually appealing images.
