2015-02-05 17:16:12 -0600	asked a question	Metal Defect Detection Hi Guys, I am trying to develop a machine vision project about cartridge inspection. I need some help about defect detection techniques. This is one of sample images: I try to find cardridge area with adaptive threshold. I extracted the inner of cartridge using adaptive threshold. My questions about defect detection techniques The surface have a texture, but small points aren't defect. Do you have a good idea to find defects on surface? Should I dissect the cartridge ROI or is there any good method inspect whole cartridge ROI at once? Thanks.
