Member Function Documentation

getNoise()

virtual float getNoise ( const Pixel & ) const

inlinevirtual

Return the noise value for a given pixel.

Definition at line 44 of file NoiseMap.h.

{ return m_noiseLevel; }

getSignificance()

float getSignificance ( const Pixel & px ) const

inline

Return the significance of a signal, that is signal divided by noise level.

Definition at line 41 of file NoiseMap.h.

{ return px.getCharge() / getNoise(px); }

operator()() [1/2]

bool operator() ( const Pixel & px, float significance ) const

inline

Check wether a signal exceeds a given significance.

Parameters

px	pixel to check
significance	minimum significance

Definition at line 50 of file NoiseMap.h.

{ return getSignificance(px) >= significance; }

operator()() [2/2]

bool operator() ( float signal, float significance ) const

inline

Check whether a signal exceeds a given significance using the average noise level.

Parameters

signal	signal to check
significance	minimum significance

Definition at line 56 of file NoiseMap.h.

{ return signal / m_noiseLevel >= significance; }

setNoiseLevel()

void setNoiseLevel ( float noise )

inline

Set the noise level.

Definition at line 33 of file NoiseMap.h.

{ m_noiseLevel = noise; }

setSensorID()

virtual void setSensorID ( VxdID )

inlinevirtual

Set the sensorID currently used.

Should be utilised later or in derived classes to obtain the correct noiseMap.
