Signal detection theory a widely accepted alternative to the high threshold model was developed in the 1950s. We may or may not use feature detection in signal detection experiments, but feature detection is describing a cognitive process of perception alone. By allowing a pfa of 0.5, the pd is increased to 0.85. The threshold parameter is the number of standard deviations from the moving mean above which the algorithm will classify a new datapoint as being a signal. In signal detection theory, f0(x) can be seen as the distribution of the output of a filter when noise alone is present in the input, and f1(x) is this distribution when a signal is present in the threshold x* is set so as to minimize the probability of either type of decision error, misses or false alarms.
