LatticeAddNoise.h

This class allows you to add noise from one of many enumerated types to a Lattice. If the Lattice is Complex, then the noise is added to real and imaginary separately.

Example

    Vector<Double> pars(2):
    pars(0) = 0.5;          // Mean
    pars(1) = 0.2;          // Variance
    LatticeAddNoise lan(Random::NORMAL, pars);
    ArrayLattice<Float> lat(IPosition(2,100,100));
    lan.add(lat);

Member Description

LatticeAddNoise()

Default constructor

LatticeAddNoise (Random::Types type, const Vector<Double>& parameters)

Constructor. An exception will occur if we cannot generate the distribution (e.g. illegal parameters).

LatticeAddNoise (const LatticeAddNoise& other)

Copy constructor (copy semantics)

LatticeAddNoise& operator=(const LatticeAddNoise& other)

Assignment (copy semantics)

~LatticeAddNoise()

Destructor

void set (Random::Types type, const Vector<Double>& parameters)

Set a new distribution. An exception will occur if we cannot generate the distribution (e.g. illegal parameters).

void add (MaskedLattice<Float>& lattice)
void add (MaskedLattice<Complex>& lattice)
void add (Lattice<Float>& lattice)
void add (Lattice<Complex>& lattice)

Add noise of given type to lattice. For Complex, the noise is added to real and imaginary separately. Any mask is ignored when adding the noise. I.e. noise is added to masked pixels.

void addNoiseToArray (Array<Float>& data)
void addNoiseToArray (Array<Complex>& data)

Add noise to array. For Complex, noise is added to real and imaginary separately.

void makeDistribution ()

Make noise generator
