java.lang.Object
- net.imglib2.algorithm.convolution.fast_gauss.FastGaussCalculator

```
public class FastGaussCalculator
extends Object
```
This class implements the fast Gauss transform to calculate a gaussian blur. The approach is very different from an algorithm using a truncated convolution kernel. Especially the runtime is independent of sigma.
The implemented algorithm is described in detail in: Charalampidis, Dimitrios. "Recursive implementation of the Gaussian filter using truncated cosine functions." IEEE Transactions on Signal Processing 64.14 (2016): 3554-3565.
