Constructor Details

BatchIndirectDistanceImpl

public BatchIndirectDistanceImpl(HumanFace gaugeFace,
 int numFaces,
 BatchDistanceNearestNeighbors.DistCache<?> distCache)

Constructor.

Parameters:

gaugeFace - A face serving as a "gauge". It is usually an average face of a set of faces.

numFaces - The number of faces to be measured (excluding the gauge face)

distCache - Distance cache
