Class DistanceHomographyPixelSq

java.lang.Object

boofcv.alg.geo.robust.DistanceHomographyPixelSq

All Implemented Interfaces:

DistanceFromModel<Homography2D_F64,AssociatedPair>

public class DistanceHomographyPixelSq
extends java.lang.Object
implements DistanceFromModel<Homography2D_F64,AssociatedPair>

Computes the Euclidean error squared between 'p1' and 'p2' after projecting 'p1' into image 2. Input points must be in normalized image coordinates, but the output error will be in pixel coordinates.
