Abstract:

An adaptive underwater dam image crack edge detection algorithm, which was based on multi-structures and multi-scale elements, was presented for the deficiencies of regular and single structure elements edge detection. Firstly, six representative structure elements were constructed and the structure elements were expanded by multi-scale analysis method. Then, multi-structure and multi-scale elements were used to detect crack edge separately. The adaptive weighted coefficients were determined by the edge information entropy. Finally, the image edges can be obtained by the synthetic weighted existing edges method. The experimental results demonstrate that the proposed algorithm not only can remove the noise effectively but also maintain the image edge detail well.
