Description Matthias Wieser 2006-05-23 22:51:43 UTC
Version:           1.5.1 (using KDE KDE 3.5.2)
Installed from:    SuSE RPMs
OS:                Linux

I'm using Krita 1.5.1 and it's Restoration filter.

Two things:
1. There is a new version of cimg available with much improved (speed, quality) restoration algorithms.
2. There is a bug which leads to 45° "motion blur" of the resoration filter. (see attachement) Increasing the iterations (e.g. "5") makes the problem more visible.

Krita plugin: standard settings

even with only one iteration a slight 45° "motion blur" effect is visible.

This quality (and even better, see
http://www.greyc.ensicaen.fr/~dtschump/greycstoration/guide.html ) could be
achieved with the new cimg 1.13 lib.

Comment 6 Cyrille Berger 2006-07-17 18:34:41 UTC
as for the bug, the code of this plugins is too horible for me :( (I will change it to work on 16bit channels, but that's all I can do)
Comment 7 Halla Rempt 2008-10-26 11:13:12 UTC
Moved to playground since it's a high-maintenance filter and none of us have got time for it,
