A Binarization Method for Crack Detection in a Road Surface Image with the Fractal Dimension
نویسندگان
چکیده
A new binarization method for crack detection in road surface image is proposed. A road surface image is consist of high frequency textures due to it's rough surface and some cracks which can have wide variation of it's form, depth, width and direction. So it is dicult to nd threshold value to discriminate a background and a crack region by conventional methods based on gray level histgram. As a result of our new technique, we could get a ne quality binarized image. In the algorithm for deciding threshold value, fractal dimension is used to evaluate the neness of binarized image locally and globally. We describe about the algorithm,test images and experimental results and compare with other binarization method.

The elements of the concrete structure are most frequently affected by cracking. Crack detection is essential to ensure safety and performance during its service life. Cracks do not have a regular shape, in order to achieve the exact dimensions of the crack; the general mathematical formulae are by no means applicable. The authors have proposed a new method which aims to measure the crack dimen...
