List of all members.

Public Member Functions

• BlockDiffHalfPel (const PicArray &ref, const PicArray &pic)

  Constructor, initialising the reference and picture data.
  

• ~BlockDiffHalfPel ()

  Destructor.
  

• float Diff (const BlockDiffParams &dparams, const MVector &mv)

  Do the difference, returning SAD.
  

• void Diff (const BlockDiffParams &dparams, const MVector &mv, const float mvcost, const float lambda, MvCostData &best_costs, MVector &best_mv)

  Do the actual difference, overwriting the best MV so far if appropriate.
  

Private Member Functions

Member Function Documentation

void dirac::BlockDiffHalfPel::Diff	(	const BlockDiffParams &	dparams,
		const MVector &	mv,
		const float	mvcost,
		const float	lambda,
		MvCostData &	best_costs,
		MVector &	best_mv
	)			[virtual]

Do the actual difference, overwriting the best MV so far if appropriate, and bailing out if we do worse

Parameters:

dparams

block parameters Parameters: mv  the motion vector being used Parameters: mvcost  the (prediction) cost of the motion vector mv Parameters: lambda  the weighting to be given to mvcost Parameters: best_costs  the best Lagrangian costs obtained yet Parameters: best_mv  the MV giving the best Lagrangian costs so far

Implements dirac::BlockDiffUp.
