Stack Blur in MATLAB

[RoyiAvital]

Hello, Is there an implementation of Stack Blur in MATLAB?
Could it work with 16 BIT images / Floating Point?

I'm interested in it here: https://github.com/RoyiAvital/FastGuassianBlur

Unfortunately I don't speak MATLAB but I am pretty sure it is possible to port it - the code just uses basic operations and no special native codes or additional libraries.

It could also work with 16 bit images or floats, but in that case the fast integer divison has to be replaced with a regular division and the handling of premultipled alpha should at least be considered as a potential place for errors.

Hi, Where can I find a description of the algorithm? Thank You.

Hi! I have written a slow, but correctly working implementation in Matlab recently. Click to download the .m file Click here to check the blur effect
