Member Function Documentation
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 |
Implemented in dirac::BlockDiffEighthPel, dirac::BlockDiffQuarterPel, and dirac::BlockDiffHalfPel.
