Is smoothing the pictures with Gaussian kernels used in deep learning and CNNs or it is just for traditional image processing methods? I haven't seen anyone using them in pre-processing for a
Why does a linear filter work well to reduce the noise for the Gaussian case but not salt-and-pepper noise? - Quora
