The object of the research is cylindrical diode. The black tube mainly contain seven kinds ofshape and texture defects, including pipe sizes, pipe defects, missing text, sheet printing, polarring missing, polar white plastic ring width inconsistencies and dew white colloid. Using themethod of image processing and pattern recognition to defect the diode, the object of thedefections is to determine whether the object is defective, and which type of the defects.
The key to solving the problems lies in two ...
