Description
Currently all selectors assume that only valid quality values are passed to them. However, double.Nan and double.Infinity values can occur by a division through zero, logarithm of a negative number, etc. and are processed by the selectors without any notification yielding in an unpredictable behavior of the algorithm. Therefore, a check for invalid quality values should be added to all quality dependent selectors that throws an exception to avoid implementation errors.
