Title: The Innovative Contributions of Dunbi Huang
Introduction
Dunbi Huang is a notable inventor based in Zhejiang, China. He has made significant contributions to the field of video coding, particularly through his innovative patent. His work reflects a deep understanding of the Human Visual System and its application in technology.
Latest Patents
Dunbi Huang holds a patent for "Adaptive quantization for perceptual video coding." This invention involves a perceptual video coder that processes local video content by calculating feature indices for various aspects of a video unit. Each feature index is mapped to a delta quantization parameter (QP) using a linear fractional model. This model establishes a relationship between the delta QP and a Human Visual System insensitivity index. The adaptive quantization is refined by adding each delta QP, allowing for improved video quality based on the refined QP.
