Abstract
► A local annular contrast based real-time inspection algorithm for steel bar surface defects. ► A gray-level comparison between the detection point and its surrounding pixels at a certain distance. ► The threshold changes with the gray-level variation of local annular background. ► The algorithm has high detection success rate and need little time.
