Characteristics in the Fourier spectrum of images associated with discontinuities such as cracks and fissures in concrete structures.

Abstract

Increasing An algorithm is developed to identify differences between concrete slabs with some type of Crack and Fissure discontinuity. The Fourier transform is used as a basis. Different types of fil-ters were evaluated within the image processing algorithm, in order to adapt favorably to the discontinuity detection process, allowing the image data to be read in the frequency domain, generating a figure of merit to compare the image. where there are no discontinuities and those that have some alteration in their structure.
