Grain Analysis Overview

Standard Grains: These grains are identified by examining the local darkness or brightness along their boundaries. This method focuses on the contrast between the grain and its surrounding area to determine its presence.

Contrast Grains: Detection of these grains is based on the grayscale or color contrast between adjacent grains. This approach highlights differences in color or shade to identify distinct grains.

Complex Grains: These grains are recognized by analyzing local complex pattern differences, such as twinning. This method involves identifying intricate patterns within the grain structure to differentiate them from others.
