Just remember that the Fourier transform puts the origin at the 4 corners and your way is not doing a low pass filter unless you've called fftshift() to get the Hglp array to put the origin at the center of the array. VERY IMPORTANT! Or else you're doing a high pass filter instead...
In this study, a low pass Gaussian type space-time filter is applied to the Navier-Stokes equations. Such an application will enhance the capabilities of simulating complex flows by eliminating the small scales of motion that cannot be resolved within the available computational grid. The ...

Progressive Gaussian low-pass filter control 在经过多个致密化步骤后, 由于自适应密度控制, 高斯基元数呈指数级增加, 这可能会导致出现与 DSV 初始化类似的问题. 为了引导高斯基元从低频到高频学习, 并让高斯基元在训练的早期阶段充分探索低频分量, 文章提出了一种高斯低通滤波器的渐进控制方法, 该方法用于渲染阶段...

We describe the Gaussian filter and its implementation in this chapter. The time domain representation (or the weighting function) of the filter is provided. The frequency domain representation (or the transmission characteristics) is also provided. Examples in this chapter show how the time and fre...
