Result of the FINE algorithm applied to Monte-Carlo simulated grayscale fiber images containing one to five fiber families. (a) Representative images with one to five fiber families. Mean fiber orientations are indicated by arrows in the bottom, left corner. (b) Calculated local main orientation in false colors. (c) The mean number of fiber families estimated by the algorithm. Error bars represent the standard deviation. The percentage of images for which the number of estimated fiber families matches the number of defined fiber families is specified at the top. (d) The amplitudes of each identified fiber family. Error bars represent the standard deviation. Expected amplitude levels at 1, 0.5, 0.33, 0.2 are marked with dotted lines. Note that amplitudes below a value of 0.01 are removed for the sake of clarity.
