Method of extracting circular region from fringe image |
摘要 |
A circular region extracting method captures onto a coordinate system a fringe image of a sample having a circular region to be analyzed within an area to be observed, binary-codes the fringe image of the area by a fringe analysis method on the coordinate system, places a plurality of linear gratings in parallel with each other with a predetermined interval on thus binary-coded coordinate system, and uses the linear gratings so as to extract a circular image region representing the region to be analyzed on the coordinate system.
