Long Term Goals

  • Establish a data structure for the quantification of Poly-3-hexylthiophene (P3HT) thin film morphology

Determine Orientation

See An algorithm for segmentation of images containing non-overlapping fibrilar domains Bin the angles like so: Bin 1: 90º or -90º .. basically straight up or down Bin 2: -45º Bin 3: 0º horizontal Bin 4: 45º Bin 5: amorphous

Spatial Statistics

There are five micro states, a 5x5 matrix of spatial stats.

Began with independent stats, so the fist four elements in teh first coloumn.

  • 1-1 autocorrelation
  • 1-2 cross correlation
  • 1-3 cross
  • 1-4 cross

PCA

Autocorrelation of 90 degree fiber in the PC1

90 auto

Cross correlation of 90 and 45 degrees in PC1

90- 45

Cross correlation of 90 and 0 degrees in PC1

90-0

Autocorrelation of 90 degree fiber in the PC2

90-90 PC2

PCs vs Mobility

We see that the structure with the highest PC1 score has highest mobility.
