Cell distribution evaluation. Results from the randomness evaluation step. Above plot: distribution of ellipse areas (representing biological object areas) in pathological tissue images. On the x-axis the distribution of objects area values is plotted; the y-axis shows the number of objects presenting the same area. Seven different sub-images are considered (line graphs) reported in the side legend, together with signals of standard deviations (singletons). Below plot: distribution of ellipse areas (representing biological object areas) in morphologically well structured tissue images. On the x-axis the distribution of objects area values is plotted; the y-axis shows the number of objects presenting the same area. Three different sub-images are considered (line graphs) reported in the side legend, together with signals of standard deviations (singletons). The red line crossing both plots represents the chosen threshold, which clearly separates among areas distributions retrieved from normal and pathological tissues.
