Title: Innovations of Shiqi Wang in Video Coding
Introduction
Shiqi Wang is a notable inventor based in Hong Kong, China, recognized for his contributions to video coding technology. With a total of two patents, Wang has developed innovative methods that enhance the efficiency and performance of video coding systems.
Latest Patents
Wang's latest patents include a method based on global rate-distortion optimization for rate control in video coding. This method provides a scheme for High Dynamic Range (HDR) in High Efficiency Video Coding (HEVC). It utilizes a rate-distortion model based on HDR-Visual Difference Predictor (VDP)-2 for performance optimization. The optimization process directly employs the parameter lambda rather than the bit rate to achieve a globally optimal solution. The model parameter estimation method is also used to minimize errors, resulting in an average bit rate reduction.
Another significant patent is a method based on coding tree unit (CTU) level rate-distortion optimization for rate control in video coding. This method effectively improves perceptual rate-distortion performance and coding efficiency. A perceptual rate-distortion model is established using a divisive normalization framework, which characterizes the relationship between local visual quality and coding bits. The established model is then applied to overall distortion optimization, transforming it into a global optimization problem solved with convex optimization algorithms to achieve optimal CTU level coding bit allocation.
