In the menu View/Statistics (fig. 17) some statistics about the distribution of an image's greyscale values are presented.
Figure 17: Image statistics menu
Fig. 18 shows the relative frequencies of the image's greyscale values.
Figure 18: Histogram of the greyscale values
One can choose between four different types of histograms. Fig. 18 shows type 3.
The coocurence matrix (fig. 19) presents the number of certain greyscale values in the neighbourhood of other greyscale values. In fig. 19 there are 241 pixels with greyscale value 1, which are follwed by pixels with greyscale value 2 to the right.
Figure 19: Cooccurence matrix with option right
The option Bottom (fig. 19) counts the pixels in the bottom neighbourhood. With the Square option every pixel in the top/bottom and left/right neighbourhood are considered. They are counted, if at least one pixels fits the condition.
