<br/>This kernel is useful for a two pass algorithm: First, perform a horizontal blur with the weights below and then perform a vertical blur on the resulting image (or vice versa).<br/>

Below is a 3×3 pixel 2D Gaussian Kernel also with a sigma of 1.0. Note that this can be calculated as an outer product (tensor product) of 1D kernels:
