Title: Shuuichi Matsumoto: Innovator in Video Coding Technology
Introduction
Shuuichi Matsumoto is a prominent inventor based in Saitama, Japan. He has made significant contributions to the field of video coding technology, particularly through his innovative patent that enhances image quality.
Latest Patents
Matsumoto holds a patent for a "Quantization control system for video coding." This invention optimizes bit allocation based on visual priority, which accurately reflects human visual characteristics for videos. The system improves the subjective image quality of the entire image, even when limited to a small number of bits. The process involves extracting an object from an input image and calculating a gaze parameter for that object. Additionally, it calculates a texture attribute parameter for each macroblock within the object. These parameters are then used to determine a visual priority parameter for each macroblock, which ultimately informs the quantization parameter.
