Member Function Documentation

correlation()

double PointMatchTriplet::correlation

(

)

const

Get method for correlation.

Definition at line 18 of file PointMatchTriplet.cpp.

{
  return m_correlation;
}

operator<()

bool PointMatchTriplet::operator<

(

const PointMatchTriplet &

other

)

const

Comparison operator for sorting lists of this class using qSort.

Definition at line 23 of file PointMatchTriplet.cpp.

  // compensate by comparing correlations numerically and flipping the result

    isLess = (m_x < other.x());

  }

  return isLess;
}

point()

QPoint PointMatchTriplet::point
