The right parameters setting to test feature detectors

Results of the evaluation of feature detectors depend on the values we give to their parameters, like the threshold , the number of octaves... How can I know which values are best? Some articles say that they use the values that the detectors' authors have used to evaluate them, but what are these values for the FAST, SURF and BRISK?
