Application of image processing technology to material evaluation is useful in determining the shape features of a material. A summary of image processing techniques applied to material evaluation and the examples of application of these techniques are introduced. In association with our practical application to material evaluation, the following three findings have been obtained: (1) By applying a pattern matching technique to the recognition of etch pits, the accurate quantitative data can be extracted from indistinct picture images of etch pits; (2) Through discrimination between brittle fracture surfaces and ductile fracture ones using a texture analysis technique, it is possible to measure the crystallinity of Charpy fracture appearance; and (3) By applying a stereovision technique, the three-dimensional shape of metal powders can be reconstructed by using the SEM stereograph. The outline of a real-time general purpose image processing system is also reported.
