Edge Detection In Pavement Crack Image With Beamlet Transform

Abstract

This paper proposed a beamlet-based method of extraction from pavement crack images. Fitstly, we transfer the collected pavement crack images to the binary images using Otsu's thresholding segmentation algorithm, then the beamlet transform was exploited to extract the linear features of cracks from the binary images with different scales and thresholds. Experiments show that the proposed algorithm can achieve satisfactory performance in the cases of low signal-to-noise ratios. ,
