The clean-up procedure, illustrated with the phase map (austenite in yellow, martensite in blue) superimposed on the confidence index (CI), whereby the highest CI is transparent and the lowest is black. (a) Raw data, (b) after CI standardization with a grain tolerance angle of 5° and a minimum grain size of four pixels, (c) after neighbour CI correlation with a limitation of 0.1, and (d) after grain dilation with a grain tolerance angle of 5° and a minimum grain size of four pixels. |
