Summary: workflow for camera(!!) related picture dead pixel
correction or dust on a lens
Platform: Kubuntu Packages
Component: Image Editor
Assignee: digikam-devel at kde.org
Reporter: axel.krebs at t-online.de
digital cameras use sensors with many pixels - millions of these are standard
I suggest to develop a workflow which could correct many of these visual
defects (more ot less) automatically.
Steps to Reproduce:
1. dead pixels or dust may appear without announcement (suddenly) on a picture
2. theses/concept idea: if comparing two pictures, there must be a situation,
where the first one is still ok, and the subsequent picture is affected (dust
on a lense, e.g.)
digiKam does not take care of such picture defects.
digiKam should (could?) automatically repair such mistakes.
Which defects I am thinking of?
- dead pixels (https://en.wikipedia.org/wiki/Defective_pixel)
- dust on a lens, filter, etc.
All these defects appear on the pic later.
They appear on all pictures from a certain begin on.
Tools for picture repair under.
A reasonable strategy could be to compare pictures pairwise, to extract "common
picture information" which would be the difference of two pics containing the
fault, I want to differentiate out.
