Detailed Description

A class for encapsulating coefficient data, derived from TwoDArray..


Constructor & Destructor Documentation

dirac::CoeffArray::CoeffArray  )  [inline]
 

Default constructor creates an empty array.

dirac::CoeffArray::CoeffArray int  height,
int  width,
CompSort  cs = Y_COMP
[inline]
 

Contructor creates a two-D array, with specified size and colour format.

dirac::CoeffArray::~CoeffArray  )  [inline]
 


Member Function Documentation

const SubbandList& dirac::CoeffArray::BandList  )  const [inline]
 

SubbandList& dirac::CoeffArray::BandList  )  [inline]
 

const CompSort& dirac::CoeffArray::CSort  )  const [inline]
 

float dirac::CoeffArray::PerceptualWeight float  xf,
float  yf,
CompSort  cs
[private]
 

void dirac::CoeffArray::SetBandWeights const EncoderParams encparams,
const PictureParams pparams,
const CompSort  csort
 

Sets perceptual weights for the subbands. Takes into account both perceptual factors (weight noise less at higher spatial frequencies) and the scaling needed for the wavelet transform.
