International Journal of Signal and Imaging Systems Engineering (IJSISE), Vol. 4, No. 4, 2011

Abstract: The Paper, the proposed research experimentation has been established in Central Foundry Forge Plant (CFFP) of Bharat Heavy Electrical Ltd. India (BHEL). The proposed image segmentation techniques are introduced to detect and assess the weld flaws from the weldments and calculate the features such as length, width, area, perimeter, major axis length, minor axis length, orientation and resolution. Software has fully written in Matlab. A comparative table showing the results is also presented in the paper. The proposed algorithm is faster and achieves favourable results. The results are validated with standard Non-Destructive Testing (NDT) methods.
