WebJun 19, 2024 · On the bottom row, we use a Gaussian filter with σ = 1 (left) and σ = 2 (right). The bottom-right image follows the rule above, and nicely suppresses all frequencies that cannot be represented properly in the downsampled image. The bottom-left image uses σ = 1 / 2 s, leading to some aliasing.
