Automatic Road Crack Detection Using Random Structured Forests

no code implementations IEEE Transactions on Intelligent Transportation Systems 2016 Yong Shi, Limeng Cui, Zhiquan Qi, Fan Meng, and Zhensong Chen

Our contributions are shown as follows: 1) apply the integral channel features to redefine the tokens that constitute a crack and get better representation of the cracks with intensity inhomogeneity; 2) introduce random structured forests to generate a high- performance crack detector, which can identify arbitrarily com- plex cracks; and 3) propose a new crack descriptor to characterize cracks and discern them from noises effectively.
