This function is ran in case that no possible thresholds were found.

NullListOfThresholds returns a threshold in the case where list_of_possible_threshold was null. It finds the first local minima, but also finds the inflection points of the density function, and returns as threshold the min of these: min(local_minia, inflection_point)

Usage

NullListOfThresholds(all_ratio_differences)

Arguments

all_ratio_differenves

An array: the ratio differences for all pairs of segments.
