Title: Yi Yang: Innovator in Image Processing Technologies

Introduction

Yi Yang is an accomplished inventor based in West Lafayette, IN (US). He has made significant contributions to the field of image processing, holding a total of 2 patents. His work focuses on enhancing the accuracy and efficiency of image defect detection and color registration.

Latest Patents

One of Yi Yang's latest patents is for an apparatus designed for image region of interest defect detection. This innovative device includes a processor and memory that store computer-readable instructions. When executed, these instructions enable the processor to access a master image and receive a corresponding scanned image. The processor identifies defects in the scanned image's region of interest (ROI) based on the master image. The types of scanned image ROIs can include raster, symbol, background, and color vector ROIs. The processor also determines the severity of the identified defect and outputs this information.

Another notable patent addresses color plane misregistration determinations. This device includes a printing mechanism that generates an image on a substrate from a digital image. The processor receives a scanned image of the printed image and identifies various image portions. It detects horizontal and vertical color changes across these portions and compares them to the corresponding changes in the digital image. This comparison allows for the measurement of color plane misregistration, including its color, direction, and magnitude.
