Figure 6.

Representative area normalized distributions of $I\left(\theta \right)$ determined from the 2D Fourier transform of the images are shown for day 1 (blue), 3 (red), and 14 (green) of observation from collagen gels with initial collagen concentration of (a) 1, (b) 2, and (c) 3 mg/ml. Note that the shape of these distributions does not change significantly over time.
