Crack Detection Using Image Processing Algorithm in MATLAB

R. Kamaleshwari, M. Nithya, M. Renuga, T. Shanmgapriya, Dr. N. J. R. Muniraj


Welding structures are nowadays used in many applications such as machineries in industry and in the form of bridges in civil structures. Crack in those structures results in loss of structural integrity which   reduces a efficiency of a system in which the structure is used. Hence crack detection of a structure before implementation is important to reduce a defect. Here adaptive changing and morphology is used to detect a crack in structures.
