Fast Gaussian Blur in pure JavaScript, via IIR filer. Speed does not depend on blur radius.
npm install glur --saverequire('glur')(src, width, height, radius)
- src - typed array with image RGBA data (will be updated with blured image).
- width - image width.
- height - image height.
- radius - blur radius.
require('glur/mono16')(src, width, height, radius) - the same as above, but
input data is grayscale Uint16Array. Can be useful to calculate unsharp mask via
brightness/ligthness channel.
- IIR Gaussian Blur Filter Implementation using Intel® Advanced Vector Extensions - very good article with technical details for programmers.
