Automated Image Quality Inspection

Image quality measurement method using natural target that 3DLabs has developed make up for the problem of existing methods of naked eye analysis and edge analysis using artificial target. And it can yield the objective indicator by automatic process. The method consists of four steps. The edge extraction step is the first step for detecting edges of natural targets using line detection algorithm. The second step is the edge profile extraction step. This step extracts the edge profiles for the edge analysis using the vertical direction extraction method. The edge profile acquired by the previous step is assessed the suitability for image quality measurement in the third step. And the edge profile selected finally yields image quality parameters by the last step.
