gaussianblur

In this question I asked how to implement a chain of blurs in one single step. Then I found out from the gaussian blur page of Wikipedia that: Applying multiple, successive gaussian blurs to an image has the same effect as applying a single, larger gaussian blur, whose radius is the square root of the sum of the squares of the blur radii that were actually applied. For example, applying successive gaussian blurs with radii of 6 and 8 gives the same results as applying a single gaussian blur of radius 10, since sqrt {6^{2}+8^{2}}=10. So I thought that blur and singleBlur were the same in the

I'm attempting to use the filters from this code http://bl.ocks.org/nbremer/0e98c72b043590769facc5e829ebf43f . The achieved effect is good in Firefox 56 (64bits) on Win 7, but it is strange in Chrome 62 (64bits). The colors are much lighter and the effect doesn't look as smooth as in FF. I've read a lot of questions about Safari not displaying these filters correctly, but I can't find anything about Chrome. Please see screenshots below : Firefox Chrome Any idea what is causing the difference and how to fix it in Chrome ? The Color Matrix filter applied reads <feColorMatrix mode="matrix" values

In cocos2d-x I need to implement fast gaussian blur and here is how it should looks like( I just found some game on the App Store with already done such blur, in unity): So, it's nice fadeIn - fadeOut blur when user pauses the game. GPUImage already has a fast blur I need, but I can't find solution for cocos2d-x. v1 code when it was (GPUImage v1) Objective C v2 code when is now Swift(GPUImage v2) Swift GPUImage-x C++

I recently learn opengl es 2.0, and now I try to make a gaussian blur on triangles generate by myself. I have some difficult to understand examples on the web and most apply the blur on an image. I know I have to use framebuffer but I don't know how to draw triangle on this and apply blur. Is it possible to see a real and complete code in C++ with good explication ?

With the advent of Microsoft's Fluent Design System and the propagation of the new Acrylic Material around the Windows ecosystem, I thought it would be great to use it in some Web layouts. Acoording to the spec , the composition of an acrylic layer is: So I went to try a CSS-only approach inspired by the layers in that picture, this way: body { margin: 0; font: 1em/1.4 Sans-serif; background: url("https://cdn.pixabay.com/photo/2017/03/27/16/50/beach-2179624_1280.jpg") center center; background-size: 100vw auto; } main { display: flex; align-items: center; justify-content: center; height: 100vh

I want to blur my image using the native Gaussian blur formula. I read this , but I am not sure how to implement this. How do I use the formula to decide weights? I do not want to use any built in functions like what MATLAB has Writing a naive gaussian blur is actually pretty easy. It is done in exactly the same way as any other convolution filter. The only difference between a box and a gaussian filter is the matrix you use. Imagine you have an image defined as follows: 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44
