Constructor & Destructor Documentation
◆ GaussianFilter()
|
inline |
The default constructor.
- Parameters
-
width The filter width defaulted to 3.0. sigma The filter standard deviation defaulted to 1.0.
References Murl::Math::Sqrt(), and Murl::Math::TWO_PI.
Member Function Documentation
◆ Apply() [1/2]
Apply the filter horizontally.
- Parameters
-
dValH The horizontal distance in range [-filterWidth .. filterWidth].
- Returns
- e^((-dValH^2) / (2 * sigma^2)) / (sqrt(2 * Pi) * sigma) or zero if distance is out of range.
Implements Murl::IFilter.
References Murl::Math::Abs(), Murl::Math::Exp(), and Murl::Util::Filter::mWidth.
◆ Apply() [2/2]
Apply the filter horizontally and vertically.
- Parameters
-
dValH The horizontal distance in range [-filterWidth .. filterWidth]. dValV The vertical distance in range [-filterWidth .. filterWidth].
- Returns
- e^((-dValH^2 + dValV^2) / (2 * sigma^2)) / (2 * Pi * sigma^2) or zero if distance is out of range.
Implements Murl::IFilter.
