A grid (e.g., square or cross-hair grid) is applied over the image, typically seen through a microscope eyepiece or on a screen. Determining if a material failure was caused by
Automated software struggles when phases have similar grayscale values, uneven etching, or complex morphology. The human eye excels at distinguishing boundaries where software fails. astm e56219 pdf
Points that fall entirely within the phase of interest are counted as 1.0 , while points falling exactly on a phase boundary are counted as 0.5 .
