Detailed Description
template<typename elemT>
class stir::SeparableGaussianImageFilter< elemT >
A class in the DataProcessor hierarchy that implements Gaussian filtering.
As it is derived from RegisteredParsingObject, it implements all the necessary things to parse parameter files etc.
The discretised densities that will be filtered are supposed to be on a Cartesian grid. The filtering operation is then performed as 3 separate 1d filters in every direction.
- Warning
- This class is currently restricted to 3d. This is mainly because of the difficulty to give sensible names to the parameters used for parsing in n dimensions.
- See also
- SeparableGaussianArrayFilter for what a Gaussian filter is
