METHOD FOR PARTITIONING AREA, AND INSPECTION DEVICE

摘要

A user is caused to designate a part of pixels in an area that should be a foreground as a foreground designating pixel, and a foreground color distribution and a background color distribution are estimated based on a color of the foreground designating pixel. Estimation processing includes a step of dividing the color distribution of the image into plural clusters, and a step of selecting at least one cluster having a large relationship with the foreground designating pixel designated by the user in the plural clusters as the foreground color distribution and of selecting at least one cluster having a small relationship with the foreground designating pixel as the background color distribution.
