Crack Width Measurement Using Unified Image Processing Techniques for Aging Structures

Abstract

Aging structures are structures that have been standing for several years already and even functional until this day. A crack is an early sign for the life prediction of the safety of a structure. The traditional method for monitoring of cracks is by visual inspection which can sometimes lead to data inconsistency. The researchers have proposed a crack recognition and measurement algorithms using several image processing techniques using bilateral filter as well as connected-component labelling and thresholding. Results showed an approximate of 90% in accuracy of crack recognition in the sample photos taken.
