DeOrbIt: synthesize replacements for Fuji-like white orbs
Note: This static page is the primary entry to DeOrbIt.
It always provides links or forwarding to the latest version of the tool.
However, we have now collected enough images to use as test cases so that
we have been able to significantly improve the tool. Links to older
versions also will be provded here. The latest version is always the
version linked here:
The versions of DeOrbIt publically available are:
A major revision of the tool based on extensive testing using images collected
with the deorbit20120307.cgi version. Although there is still room for
improvement, it is rarely necessary to adjust more than the enlarge parameter
in order to get a significantly prettier image. The greater the artifacting
around each orb, the greater the enlarge parameter should be. Very
clean images work best with 0 pixel enlargement, whereas night scenes often do
better with up to 3 pixel enlargement of regions. There is sometimes a nasty
green or red color splotch in the synthesized image; this is due to expansion
of color fringes around the orbs, and is sometimes severe enough that a future
version of the tool may add a desaturation control.... Note that the
parameters used in this version of the tool are not quite the same as those
used in the original version.
This is the original posted version. Aside from issues involving inconsistent
quality of the repairs made to images, there was a limit of 4000x3000 pixels
on image size which caused full-size portrait-orientation images to be rejected.
The C program that generated this page was written by
using the CGIC
library to implement the CGI interface.
The only thing set in stone is our name.
