Surface defect detection of steel strip based on spectral residual visual saliency
As captured images for surface defect detection of a steel strip is vulnerable to lighting conditions
weaker defect characteristics and other factors
this paper proposes a new algorithm based on spectral residual visual attention mode to complete the strip surface defect detection in real time. Firstly
the homomorphic filtering method was proposed to preprocess the image to remove the influence of uneven illumination and to perfect the subsequent segmentation results. Then
a visual-attention model was constructed to obtain the defect saliency map by applying the subtraction to the logarithmic spectrum curve. Finally
the weighted Mahalanobis distance method was proposed to significantly enhance the saliency image thresholding. These locations of the defects in the original strip defect images were marked by using the connected-component labeling method. The proposed algorithm was verified by experiments. Experimental results show that the algorithm has a fast detection speed
and takes only 37.6 ms in the single image detection
meeting the requirements of the real-time detection. The comparative experiment with the gray projection method
multi-scale Gabor edge detection method and Markortree model was carried out in the same defect database
and the results show that average detection rate of the proposed algorithm reaches to 95.3% for 8 common types of defects. In the meantime
the missing rate and false positive rate are still low. These results validate the effectiveness of the algorithm.
