Title: Yunjun Zhang: Innovator in Graphics Processing Technologies

Introduction

Yunjun Zhang is a notable inventor based in Orlando, FL, who has made significant contributions to the field of graphics processing. With a total of 2 patents, his work focuses on enhancing the efficiency and effectiveness of graphics work scheduling and processing.

Latest Patents

Zhang's latest patents include "Affinity-based graphics scheduling" and "Real-time chromakey matting using image statistics." The first patent discloses techniques related to affinity-based scheduling of graphics work. In this innovation, first and second groups of graphics processor sub-units share respective caches, allowing for improved cache efficiency. This is achieved by assigning subsets of graphics work that access the same memory areas to the same group of sub-units that share a cache.

The second patent, "Real-time chromakey matting using image statistics," outlines a method and system for real-time chromakey matting. This process involves three stages: an off-line training stage for semi-automatic calibration, a real-time classification stage for estimating the alpha matte on a GPU, and an optional error minimization stage to improve the estimated matte. The resulting matte allows for standard alpha blending, creating the illusion that virtual scenes coexist with video feeds.
