code: public static Point2D_F64 convertNormToPixel( DMatrixRMaj K, Point2D_F64 norm , Point2D_F64 pixel )
  	{
  		return ImplPerspectiveOps_F64.convertNormToPixel(K, norm, pixel);
  	}
docs: <p>
  Convenient function for converting from normalized image coordinates to the original image pixel coordinate.
  If speed is a concern then {@link PinholeNtoP_F64} should be used instead.

  NOTE: norm and pixel can be the same instance.
  
  @param K Intrinsic camera calibration matrix
  @param norm Normalized image coordinate.
  @param pixel Optional storage for output.  If null a new instance will be declared.
  @return pixel image coordinate
