An Automatic Detection by Classification of Cracked Pixels or Noncracked Pixels in Road Surface

Figure 11

Comparing different results generated by different methods of detecting the oblique cracks. M1, M2: 2 Markov-based approaches, M2 is an improved variant of M1; GC: geodesic contours based on points of interest detection; FFA: free form anisotropy based on oriented minimal paths; MPS: minimal path selection and approach proposed in the paper.
