System and Method for Automatically Detecting a Mura Defect using Morphological Image Processing and Labeling

摘要

The present invention relates to a system and a method for automatically detecting a spot defect using morphological image processing and labeling, A preprocessing unit for removing an illumination component from the image acquired by the image acquiring unit using morphological image processing; and a histogram acquisition unit for acquiring a histogram of the image from which the illumination component has been removed in the preprocessing unit A histogram smoothing unit for reconstructing an image by expanding to a whole gray level through histogram smoothing and a smoothing candidate generating unit for forming a smoothing candidate region by applying a Gabor filter to the image transformed by the image processing unit; It is possible to provide a system and a method for automatically detecting odd defect by using a video analyzing unit having a smear detecting unit for detecting a smear by using labeling in a smear candidate region formed in the candidate generating unit.
