Embodiment Construction
[0055] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0056] like figure 1 As shown, the method for detecting surface defects of sheet and strip steel based on the saliency label information propagation model of the present invention comprises the following steps:
[0057] Step 1: Collect the surface image of the strip steel to be detected, and form the surface image I of the original strip steel 0 , for the original strip surface image I 0 Carry out preprocessing, and obtain the surface image I of the strip steel after preprocessing.
[0058] In this embodiment, the surface image I of the original strip steel is 0 The preprocessing includes: using the noise reduction method DAMF to analyze the surface image I of the original strip steel. 0 Carry out noise reduction processing, then the image after noise reduction processing is converted into the RGB image of 3 channels, obtains the preprocessed...
