An artery reconstruction in upper extremities is rare performed compared to the artery reconstruction in lower extremities. Primary vascular repair was performed in many cases. As to alleviate vascular occlusion, an interposition vein graft or venous bypass grafting were applied. However, one or more the internal diameters of applied vein graft are blocked(More)
Because decisions made by human inspectors often involve subjective judgment, in addition to being intensive and therefore costly, an automated approach for printed circuit board (PCB) inspection is preferred to eliminate subjective discrimination and thus provide fast, quantitative, and dimensional assessments. In this study, defect classification is(More)
It is well-known that thresholding algorithm is needed by gray-scale images in segmentation operation. In this paper, real printed circuit boards used are captured using a monochrome charged coupled device camera and produced images consisting of foreground and background objects in gray-scale format. In order to correctly differentiate these two kinds of(More)
