Discrimination of Carbides Morphology by Optical Matched Filtering Method

Abstract

An application of optical matched filtering, which is one of the hologram techniques, to the recognition of patterns is described from the viewpoint of quantitative metallography.
The results obtained are summarized as follows:
1) The contour treatment of the input patterns is effective in the recognition of patterns.
2) The optical matched filtering method was applied successfully to determine the morphology of carbides in a high manganese cast steel.
