RealT scale;

RealT vec_subsample;

top-level motion vector display subsampling factor

RealT noise;

MultiScaleMotionC(const IPConvSymC<RealT,RealT> & Filter,const LMSOpticFlowC Flow)

Constructor:

Filter	subsampling antialias filter
Flow	optical flow engine

MultiScaleMotionC & SetFilterErode(BooleanT Erode)

Set subsample filter resize to erode (Erode==true) or no erosion (Erode==false)

NumImageC<Vector2dC> Estimate(const PairC<NumImageC<RealT>> & im,IndexC Levels = 3)

Generates optical flow field from a pair of images, using not more than "Levels" levels of hierarchy

MultiScaleMotionC Verbose(RealT VectorScale = 1,RealT VectorSubsample = 1)

Image, PostScript and data files of the o/p from each level are written

VectorScale	rescales motion vectors and ellipses in Postscript images
VectorSubsample	subsamples the displayed motion vectors; e.g. =4 will subsample the vectors by 4 at level 0, by 2 at level 1, full fesolution at level 2

NumImageC<Vector2dC> EstimateRecursive(const PairC<NumImageC<RealT>> & im,IndexC Levels)

recursively generates optical flow field from a pair of images, using not more than "Levels" levels of hierarchy

NumImageC<Vector2dC> BottomLevel(const impairT & im_pair,IndexC times)
