Image processing technique for grain boundary extraction.
Katsuhiko Sakaue · ISIJ International · 1990
This paper describes a newly developed imageprocessing program for grain boundary extraction with some experimen- tal results.It is available on an MS-DOS per80nal 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 de- signed so as to be suitable for the property of a grain images, so that the program is appiicable to many kinds of grain im- ages.Since the operators provided in the program are of general purpose inherent, it is also applicable to any kinds of digi- tal images by combining the operators as you like.
