Fastest Available Algorithm to Blur an Image (Low Pass Filter)

Web17 de jun. de 2010 · Hi, I’m trying to do a gaussian blur on an image (in OpenCL), but all the algorithms I found are for separable gaussian (the blur is done horizontally then vertically), so it’s 2 1-dimensionnal operations. I’m looking for how to perform a single pass 2-dimensionnal gaussian blur. (my gauss have to be integrated to a 2-dim kernel so a … WebThe fastest blur would be Box Blur. You can implement it using Running Sum. I think Intel FilterBoxBorder works in that manner. If you'd like you can do a few passes of it to approximate the Gaussian Blur. You can also use IIR Filter Coefficients to blur the image quite easily. You may have a look at my project Fast Gaussian Blur. camouflage blouse

Web18 de nov. de 2015 · 1 Answer. Sorted by: 1. The kind of artefacts you're seeing - the squares - are often caused by not sampling some pixels within the blur range. Since you're only using 9 samples, and your blur is quite soft, this is likely the case here. You're effectively blurring a lower-resolution image, but the next fragment over is blurring a … WebA tag already exists with the provided branch name.
