Dear Mr. Karas,


even better, but this requires uniform distribution of value or linear distribution. if that data belongs to the curve of higher degree?

y = f(x) is what table reflects.

inverting the table will give the relation

x = f^-1(y)

once this polynomial is calculated, a LUT can be built
as you suggested or if polynomial is of degree <= 2 can be calculted alternatively.
