Distribution of fractal dimension values for F-actin image of a random cell on different angles and box positions.

(a) Representative F-actin image of the cell from control group. Color points and pixel coordinates (cyan, green, red, and magenta) shows the positions of 4 box centers during box counting process. (b) dot plot shows variation of FD values which were obtained during the variation of the positioning of box centers and rotation angles. (c) notched boxplots of FD values (averaged for values obtained by varied positioning of box center and rotation angles). Black boxplot represents the cumulative FD values for all angles and box positions. Mean values are shown as color-coded crosses (x) on the boxplots. FD value (calculated using the previously described algorithm, see Methods) is shown as blue circles for comparison of the value with the medians and mean values of current FD distributions.
