Application of Undecimated Wavelet Transform to Surface Defect Detection of Hot Rolled Steel Plates

Wu, Xiu-yong, Xu, Ke, Xu, Jin-wu·2008·2008 Congress on Image and Signal Processing

Abstract

Characteristics of surface defects of hot rolled steel plates were analyzed, and an algorithm for detection of hot rolled steel plates was developed. Based on undecimated wavelet transform and mathematical morphology, the algorithm can solve the problem of false alarms by scales and water marks. Positions of defects were determined by modular maximum of inter-scale correlation of wavelet coefficient at first, and then the defects were classified with priori knowledge about characteristic of surface defects on hot rolled steel plates. Experimental results shows that the algorithm is not sensitive to disturbance of scales, water marks and uneven illumination, and the recognition rate of defects is up to 90.23%.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
