Specified by:

getTransformSrcToDst in interface MotionTransformPoint<Affine2D_F64,Point2D_F64>

Returns:

motion

process

public boolean process(List<Point2D_F64> srcPts,
 List<Point2D_F64> dstPts)

Description copied from interface: MotionTransformPoint

Processes the sets of corresponding points and finds a transformation which when applied to 'srcPts' will minimize the difference with the 'dstPts'.

Specified by:

process in interface MotionTransformPoint<Affine2D_F64,Point2D_F64>

Parameters:

srcPts - The points which are to be transformed. Not modified.
