public class FastGauss extends Object
Gauss3. It's
especially faster if sigma is larger than 3.
It's expensive to calculate the exact result of the gaussian blur. That's why
approximations are almost always used.
Gauss3 does an approximation by cutting
off the gauss kernel at 3*sigma + 1. FastGauss uses a different
approach known as fast Gauss transformation. It's runtime is independent of
sigma.
See FastGaussCalculator for more details.
