Abstract
Official abstract text for this publication.
Aspects of the present invention are related to systems, methods and apparatus for image-based automatic detection of a defective area in a flat panel display and classification of the defect type and the cause of the detected defect.
First claim
Opening claim text (preview).
What is claimed is: 1. A non-transitory computer-readable medium encoded with a computer program code for implementing a method for identifying a defect type associated with a detected defect in a flat panel display, said method comprising: receiving, in a computing device, a defect mask image associated with an image of a detected defect in a flat panel display; receiving, in said computing device, a plurality of landmark mask images, wherein: each landmark mask image in said…
