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.
