Box blur hlsl

WebThe box blur uses the mean color of the samples taken. The median filter uses the median color of the samples taken. By using the median instead of the mean, the edges in the image are preserved—meaning the edges … WebAdditionally, the blur pass should be done in 2 passes. This brings down the complexity of the algorithm from O (N 2) O(N^2) O (N 2) to O (2 N) O(2N) O (2 N). This can be done if the used blur algorithm is a so-called separable filter which is the case both for a box blur and a gaussian blur. When doing the blur in 2 passes, the pixels get ...

WebDrop shadows can also be rendered on the CPU using repeated application of a moving average box-blur to approximate a gaussian blur. This works out to O(1) cost per pixel assuming the blur radius is much less than the size of the image. Every additional box blur pass improves the approximation and in practice stopping after three passes is fine.
