Member Function Documentation

float dirac::BlockDiffHalfPel::Diff	(	const BlockDiffParams &	dparams,
		const MVector &	mv
	)

virtual

Do the difference, returning SAD

Parameters

dparams	block parameters
mv	the motion vector being used

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