If true then the score which represents the distance between two features is squared. If this flag
is true then when the score ratio is computed the square root will be used.

scoreRatioThreshold

publicdoublescoreRatioThreshold

If less than one then the best two matches are found the ratio is defined as the distance of the best
divided by the distance of the second best. Matches are only accepted if less than this ratio

maxErrorThreshold

publicdoublemaxErrorThreshold

If more than zero then this is the maximum allowed error/distance between two features for a match to
be accepted

maxNodesSearched

publicintmaxNodesSearched

The maximum number of nodes it will search in a KD-Tree. Setting a limit will improve speed at the cost
of accuracy.
