TABLE III.

Results from assessing the combination of filters. The best filters are shown for multiple positive condition rates (15, 20, and 25% correspond to filter sets A-C). Neither the maximum brightness percentile nor the maximum standard deviation percentile contributed to any of the best-case options.

Filter Set	Positive Predictive Value	Positive Condition Rate	Minimum Brightness Percentile	Minimum Speckle SNR	Minimum Frame-to-frame Correlation	Maximum Standard Deviation Percentile	Maximum Brightness Percentile
A	98.59%	15.06%	64	1.45	0.5	100 (off)	100 (off)
B	98.10%	20.76%	46	1.40	0.6	100 (off)	100 (off)
C	97.37%	25.39%	44	1.45	0.4	100 (off)	100 (off)
