Table 6 Classification performance of: (A), the current palette, taking color boundaries in the center of 'buffer' colors at 230 and 520 PU.

From: Using ordinal logistic regression to evaluate the performance of laser-Doppler predictions of burn-healing time

  1. Note that the current palette was not designed to be used in this way! For (B), the optimized palette, the flux boundaries are 241 and 452 PU. Lastly, (C), using mean flux as a classifier, flux boundaries are 250 and 465 PU.
