 note = {P(論文), This paper reports on experimental results of detection of degraded target images in digital mages for industrial vision metrology. The paper classifies the reasons of degradations. Two detection procedures, a priori and a posteriori, are applied to degraded image detection. A priori procedure is to single out them by ellipse fitting and a posteriori procedure is to detect them by so-called three-sigma criterion on residuals after adjustment. And the experiment shows that a priori procedures do not well work for typical size of images such as 5-10pixels, while the a posteriori procedure can detect half-occluding target images effectively.},
