Figure 5
The ferroferric oxide distribution calculated using the subtraction and ratio methods. The image size, step and number of pixels are 17.7 µm × 18 µm, 50 nm and 354 × 360, respectively, after shifting and clipping. The red frame areas of the two images denote the ferroferric oxide distribution. The range of ratio contrast (colourful regions) noted by the colour bar in (a) is from 1.168 to 3.606, where 1.168 is the threshold and 3.6055 is the maximum contrast ratio, while the colour bar in (b) shows the subtraction contrast from 0.087 to 0.958, where 0.087 is the threshold and 0.958 is the maximum of subtraction contrast.
