Thresholding

Thresholding was done to separate the pixels representing the fibers from the pixels representing the matrix. To determine the value for thresholding the image, a threshold scan was done in each of the three planar directions (figure below). thresholding graph

From this figure we can choose a thresholding value to apply to the images.

Code can be found at this Gist.

Problems

  • Determine optimal boundaries for cropping to keep maximum possible experimental data
  • Metric for determining if the thresholding is “good’

Next Steps

  • Choose the number of states (h)
  • Create a microstructure function
  • Determine spacial statistics on sample
