Computer Extraction and Recognition Method Research on Weld Defect

Abstract:

This paper carry out a kind of defect extraction method .Aiming at the weld image defect extraction accuracy is not high and defect feature selection is undeserved, thus affecting defect recognition rate is not high lead to falsely accused of miscarriage of justice on this condition.Based on image preprocessing to remove noise and strengthen the image, and then the image analysis so as to extract defect finally take defect marking defect feature parameter selection, in order to accurately identify defect.
