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.

const SubbandList& dirac::CoeffArray::BandList ( ) 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,
const float  cpd_scale_factor 
)

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.

void dirac::CoeffArray::SetCSort ( const CompSort  cs) [inline]
