A new method of image segmentation based on neural network was proposed to extract the cracks image
with which it could overcome
in some extent
the dependence of the background image and reduce the pseudopoints and pseudoregions. The measurement accuracy can be improved compared with that from morphological algorithm. Furthermore
the specific methods and processes to measure the walls crack with image digital processing were presented. And with the case study
it was found that this method can measure the cracks accurately with convenient operation.
