stackblur-go is a Go port of the Stackblur algorithm.
Stackblur is a compromise between Gaussian blur and Box blur, but it creates much better looking blurs than Box blur and it is ~7x faster than Gaussian blur.
The API is very simple and easy to integrate into the project. There is a single publicly exposed `Process` functions which receive an image and a radius as parameters and returns the blurred version of the provided image.
func Process(src image.Image, radius uint32) image.Image
Below is a very simple example of how you can use this package.
package main
import (
func main() {
img, err := os.Open("sample.jpg")
defer img.Close()
src, _, err := image.Decode(img)
if err != nil {
res := stackblur.Process(src, uint32(5))
output, err := os.OpenFile("output.jpg", os.O_CREATE|os.O_RDWR, 0755)
defer output.Close()
if err != nil {
if err = jpeg.Encode(output, res, &jpeg.Options{Quality: 100}); err != nil {
package stackblur
You can’t perform that action at this time.
