Hello Mirek,

Quote:

In the end, I have renamed to GaussianBlur and done some code simplification. Also added "co" parameter for parallel processing, although it does not show much perforamnce gains (less than 70% speedup on 2700x).

Thanks!

I've used the upptst/blur code and the supplied image, and other images that I have, on one of my machines with AMD FX6100, six-core processor, and I got ~3x (2.74) speedup (consistently).
While not spectacular, it is nice and noticable. Smile

I'll test it further...

By the way, that CoFor looks like a really handy addition.

Best regards,
Oblivion
