Method for eliminating scratches in cross-sectional image of cable

Abstract

The present disclosure provides a method for eliminating scratches in a cross-section image of a cable, comprising: acquiring an original image of a cross-section of the cable, the original image having a first modality; performing, by a processor, dilation and erosion on the original image to obtain a processed image, the processed image having a second modality; fusing, by the processor, the original image and the processed image to obtain a fused image; processing, by the processor, the fused image to obtain a scratch eliminated image; and applying the scratch eliminated image in actual quality detection of the cable to improve accuracy of the quality detection. By introducing multimodal features, the method relieves the loss of image information. The method can keep the information of the original image as much as possible, and can significantly improve the accuracy of cable quality detection.
