public class Quantization_float
extends QuantumStrategy

Quantization process. In charge of building a look-up table for each active wavelength. The mapping process is done in three mapping steps, for some computer reasons, we cannot compose (in the mathematical sense) the three maps directly. Each wavelength initializes a strategy, in order to preserve the 5D-notion of OME image, we first compute the normalized parameters. We determine a pseudo-decile (not decile in maths terms) interval and compute the associated parameters to reduce the irrelevant values (noiseReduction).

Since:

OME5.1
