Image Processing Technique for Grain Boundary Extraction
This paper describes a newly developed image processing program for grain boundary extraction with some experimental results. It is available on an MS-DOS personal computer without any special equipment. The program deals with image data directly, and extracts a thinned image of grain boundaries from an input original gray image. Its robustness comes from refinement process inserted between binarization and thinning. The refinement process is carefully designed so as to be suitable for the property of a grain images, so that the program is applicable to many kinds of grain images. Since the operators provided in the program are of general purpose inherent, it is also applicable to any kinds of digital images by combining the operators as you like.
