Abstract:
1. An image processing device that extracts a contour of a pattern formed on a sample that is a target of measurement or testing, the image processing device comprising: a pattern in/out definition information generation unit that performs a thinning process on design data for generating a target sample so that inside and outside regions of the pattern are narrowed and generates pattern in/out definition information defining an inside and an outside of a pattern formed on the target sample and generating the pattern in/out definition information by referencing alignment information obtained through a matching process between the target sample image and the design data; an edge enhancement unit that generates an edge-enhanced image of a target sample image obtained by irradiating the target sample with an electron beam; and a contour generation unit that performs region segmentation by expanding regions indicated by the pattern in/out definition information while referencing pixel values of the edge-enhanced image and generates a pattern contour of the target sample.
