order - algorithm to use
Euclidean distance if order is 2 (default), Minkowski distance algorithm of nth order if order is higher than 2
multiplier - by how much to enhance difference analysis in range of 1..100
default is 20 which normalizes results to similarity above 0.5 can be considered a match
min - normalize similarity result to a given range
max - normalzie similarity resutl to a given range
default is 0.2...0.8
Returns similarity between two face descriptors normalized to 0..1 range where 0 is no similarity and 1 is perfect similarity
Calculates normalized similarity between two face descriptors based on their
distance
