OK, 我们对高斯函数已经有一定的了解了,当然,本篇文章讨论的是一维,高维等用到再讨论吧。 Part2 Gaussian Filter (Complex domain) Convolution core: g(x)=a0πe−a0x2 Fourier Transform: G(f)=e^{-\frac{\pi^2f^2}{a_0}} 改写一下: G(j\omega)=e^{-\frac{\omega^2}{4a_0}} 二阶矩:...

Based on the convolution filter (CF) and similar to the Gaussian filters, the GCF approximates the posterior density of the states by Gaussian distribution. The analytical results show the ability to deal with complex observation model and small observation noise of the GCF over the Gaussian ...
First, the Gaussian kernel is linearly separable. This means we can break any 2-d filter into two 1-d filters. Because of this, the computational complexity is reduced from O(n2) to O(n). Let’s see an example Applying multiple successive Gaussian kernels is equivalent to applying a sing...
