WebJun 6, 2024 · Gaussian blurring This works similarly to Averaging, but it uses a Gaussian kernel, instead of a normalized box filter, for convolution. Here, the dimensions of the kernel and standard deviations in both directions can be determined independently. Gaussian blurring is very useful for removing — guess what? — gaussian noise from the image.
