Motion compensator class, for doing motion compensation with two references and overlapped blocks, using raised-cosine roll-off. This is an abstract class. It must be sub-classed and the BlockPixelPred must be defined in the sub-classes.

functions
Motion-compensate a component
void CompensateComponent( Picture* pic ,
Picture* refsptr[2] ,
const MvData& mv_data , const CompSort cs);
Recalculate the weight matrix and store other key block related parameters.
DC-compensate an individual block
void DCBlock( TwoDArray<ValueType> &block_data ,
const ValueType dc);
void ReConfig();
Calculates a weighting arrays blocks. void CalculateWeights(int xbsep, int ybsep, TwoDArray<ValueType>* wt_array);
Calculates a weighting block.
/*! Params defines the block parameters so the relevant weighting arrays can be created. FullX and FullY refer to whether the weight should be adjusted for the edge of an image. eg. 1D Weighting shapes in x direction FullX true FullX false
