Member Function Documentation

void GaussianFilter::init

(

)

[virtual]

Performs any initialization which may be necessary before filter evaluation.

Note:

Default implementation initializes the filter support based on its PropertyMap

Reimplemented from KernelFilter.

real_t GaussianFilter::evaluate

(

const Vector2 &

pt

)

[virtual]

Returns:

the value of this filter function evaluated at the given point

Implements KernelFilter.

Definition at line 21 of file GaussianFilter.cpp.

real_t GaussianFilter::getSigma

(

)

const [inline]

Returns:

the sigma parameter of this gaussian distribution (standard deviation)
