An Unsupervised Approach for Road Surface Crack Detection ...

Road surface distress is one of the major concerns for safety in transportation management. Surface crack is the initial stage for the structural breakdown of the asphalt pavement which may gradually deteriorate to potholes resulting in huge reforming cost in the later stage. So, detection of road surface cracks needs a good extent of attention for avoiding these inconsistency of ...
