Gaussian Blur filter.
Library: ilvbmpflt
This bitmap filter lets you perform a Gaussian Blur on an image.
The Gaussian Blur kernel is an approximation of the normalized convolution: H(x) = exp(-x^x / (2 * s^s)) / sqrt(2 * pi * s^s) where s is the user-specified standard deviation. This filter is implemented as two successive horizontal and vertical kernels. Different deviations can be given for x and y directions.
Constructor.
Initializes a new instance of the class IlvGaussianBlurFilter.
| deviationX | The deviation in the x direction. |
| deviationY | The deviation in the y direction. |
| IlvGaussianBlurFilter::~IlvGaussianBlurFilter | ( | ) |
Destructor.
The destructor releases all the memory used by the instance.
| IlFloat IlvGaussianBlurFilter::getDeviationX | ( | ) | const |
Returns the deviation in the x direction.
| IlFloat IlvGaussianBlurFilter::getDeviationY | ( | ) | const |
Returns the deviation in the y direction.
| IlUInt IlvGaussianBlurFilter::getRadiusX | ( | ) | const |
Returns the kernel radius in the x direction.
| IlUInt IlvGaussianBlurFilter::getRadiusY | ( | ) | const |
Returns the kernel radius in the y direction.
| void IlvGaussianBlurFilter::setDeviationX | ( | IlFloat | deviation | ) |
Sets the deviation value in the x direction.
| deviation | The new deviation value. |
| void IlvGaussianBlurFilter::setDeviationY | ( | IlFloat | deviation | ) |
Sets the deviation value in the y direction.
| deviation | The new deviation value. |
