50 shades of GREYCstoration (bug in older version)

[David Serrano]

To rehash old habits of mine , I think I've found a bug in GREYCstoration. But first, I'd like to point out I'm using PI 1.7.4-0759 due to PI 1.8 not working in Debian wheezy (which ships an older libc despite being the latest stable release). So the GREYC version is 01.00.02.0124. I've searched the forum and found nothing like this.



Notice how the center of the image is considerably more blurred than the upper and lower areas. To replicate, please download the original image and the xpsm, which is nothing more than a STF (to highlight the noise) and the relevant GREYCstoration instance, with default parameters and 3 iterations.

(Next post telling that this is fixed in PI 1.8 in 3, 2, 1…)

Hi David,

You have found a bug that---surprisingly---has passed inadvertent since the version you're using. It happens in the current version too, and seems to be related to parallel execution. If you disable it (enter "parallel --disable" from the console, then after you've finished testing enter "parallel --reset" to return to the normal state), the problem does not happen.

I'll see how I can fix this ASAP. Thanks for the catch (and please upgrade to a more contemporary distro, man...  )

It's the latest debian stable. Yeah I know they ship a really old libc6 (but I only learned that after installation ). I'll have to "upgrade" to testing.

Anyway thanks for the temporary fix! That mosquito is standing on water .
