Graph (a) shows the changes of the average recorded number of green dots in every DFM image with the changes of the predicated number, and the red dotted line represents the function of y = x. Graphs (b,c and d) show the changes in the number ratio of the red dots to the green dots in every DFM image when 20, 10, and 5 images are used to comprise a data point, respectively, and the blue lines is the linear fit.
