Recognition of different fracture surface morphologies using computer image processing technique

The software which enables us to classify six typically different fracture surface morphologies, such as striations, equiaxed dimples, elongated dimples, transgranular failures, intergranular failures, and cleavage failures, has been developed based upon computer image processing and pattern recognition. The texture analyses used here are the Fourier power spectrum, generalized co-occurrence matrices, the three dimensional fracture surface topographies
