Fatigue failures originating at inclusions and internal defects can lead to sudden failure of railroad wheels.Internal defects can grow unexpectedly and can lead to vertical split rim (VSR) or shattered rim crack (SRC) wheel failures,which could result in costly derailments.A robust signal processing method for quantitative high eddy current [3],magnetic particles [4],and ultrasonic testing [5] can improve the accuracy of crack detection.Nevertheless,human operations are needed as opposed to automatic and continuous fatigue crack monitoring.Other advanced technologies like acoustic emission [6] and piezoelectric sensor [7] also show potentials for crack detection;12345NextCrack detection using image processing A critical review Jun 01,2018 Automatic restraint and visual detection of fatigue crack#0183;In this section,Table 3 shows the analysis of the reviewed papers on the image processing techniques used for the crack detection in the engineering structures.Morphological approach was used by many of the proposed methodologies including ,,,and .The collection of non-linear operations (such as erosion,dilation,opening,closing,top-hat filtering,and watershed
