ABSTRACT: Recently, image processing technology has been developed into the inspection of bridges to
detect cracks. However, there are still some difficult problems unresolved, for example, noises in the concrete
bridge pictures are very similar to cracks, may be even more dominant than cracks. In this paper, an improved
method to handle this situation is proposed. A modified percolation model is used to detect
