Abstract: In the X-ray images of copper-plated polymer composite conductive microsphere, a simple and efficient automatically processing method is presented in this paper to separate overlapped microspheres and defects are extracted. Through image threshold and morphology, it counts the microspheres; based on labeling, template matching and microspheres area locating, defects are extracted by the mean gray. Experimental results indicate that, the method has the advantages of high speed, high detect precision and strong applicability.

Key words: digital radiograph, morphology, labeling, template matching
