What is use of a gaussian filter over histogram?

WebThe Gaussian assumption is used in the predict and update steps of the Kalman Filter. They are the reason you only have to keep track of means and variances. First, Z t X t is Normal. Second, X t Z 1: t − 1 is Normal. Then, by Bayes' theorem, p ( x t z 1: t) ∝ p ( z t x t) p ( x t z 1: t − 1) is Normal. Then the process begins again.

WebFor Gaussian, we know that 99.3% of the distribution falls within 3 standard deviations after which the values are effectively close to zero. So, we limit the kernel size to contain only values within 3σ from the mean. This approximation generally yields a result sufficiently close to that obtained by the entire Gaussian distribution.
