Climber-Inspired Fuzzy Logic Approach to Crack Localization Using Image Analysis

Abstract

This paper presents an alternative fuzzy logic approach to localization of cracks on a concrete surface. The exact locations of cracks are especially needed in the case of comparison between the results of numerical analyses and experiments. The proposed method is based on the fact that cracks can be considered as highlands which has to be trekked along the ridge. The problem is similar to human perception and decision making. For this reason, the use of fuzzy logic for the purpose of classification is appropriate. The whole procedure of the so-called climber method is given. The results show the capability of the proposed method to localize cracks, advantages and the possible range of application of the proposed method are discussed.
