IMAGE PROCESSING METHOD AND DEVICE FOR METALLOGRAPHIC IMAGE, AND IMAGE PROCESSING PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide an image processing method that enables evaluation of the state of crystal grains from a microscopic image of a metallographic structure by using a computer.SOLUTION: An image processing method of the present invention includes the steps of: creating a first processing image by performing gray scale conversion of an image of a metallographic structure; creating a second processing image by performing smoothing processing to the first processing image; and creating an evaluation object image by performing noise removal processing to the second processing image.
