w2kmeans::WeightingScheme Class Reference

List of all members.

Detailed Description

This class does the calculations for the spatial interpolation performed by SegmentMotionEstimator.

There is a separate object per region identified.

The weighting scheme is such that weight=1 at the boundary of the region, > 1 in the interior of the region and < 1 outside the region, falling quickly to zero beyond 2x the region boundary.
