Abstract

Abstract

Some algorithms about image processing and analysis in strip quality inspection were discussed. With plenty of strip images being captured from a hot-rolled steel strip line, evaluation and comparison to these algorithms were done with the rule of UMA (Ultimate Measurement Accuracy), which showed that the dynamic threshold image segmentation was the best and could be applied to the on-line width measurement of hot strip.
