Test 11 S/T/U Comparative Results
The measures of accuracy are plotted for each test in figures ?? to ?? under Tables and Figures (below).
Figure 1: Minima
Figure 1 illustrates the minimum uncertainty and RMSs for each test, and at which iteration each minimum occurs. The following patterns are apparent:
Test U achieves the minimum value for every measure in the least number of iterations: 5 to 15 iterations sooner than Test T; and 15 to 20 iterations sooner than Test S (excluding Test S - CompMapVec RMS).
- Test S consistently gives the largest RMS but the smallest formal uncertainty.
- CompareOBJ RMS (with and without optimal translation and rotation varies across tests by less than 0.2cm, although Test U consistently archives the minimum RMS in significantly fewer iterations.
