Abstract: In order to deal with the problem of false information and edge breakpoint about binary image of asphalt pavement crack image segmentation, a new method of discontinuity crack block linking was developed based on autonomous edge growing. This method removed false information according to the characteristics of circular noise and linearly cracks, and filled interstice by using method of region filling, thereby accomplished linking of discontinuity crack block based on autonomous edge growing. The experimental results show that the algorithm has excellent performance in edge linking of discontinuity crack block in different cases, and the noises can be removed at the same time, which is in favor of subsequent image processing such as image measurement and evaluating.
