Title: Gouichi Ishihara: Innovator in Video Coding Technology

Introduction

Gouichi Ishihara is a notable inventor based in Saitama, Japan. He has made significant contributions to the field of video coding, particularly through his innovative patent that enhances image quality. His work focuses on optimizing bit allocation based on human visual characteristics, which is crucial for improving the subjective quality of video images.

Latest Patents

Ishihara holds a patent for a "Quantization control system for video coding." This invention provides a method for optimizing bit allocation based on visual priority, which expresses human visual characteristics with high precision. The system improves the overall image quality even when limited bits are available. 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, which ultimately helps in setting the quantization parameter.
