The source
There are only minor changes to the
Makefile,
view_main.cc,
view_ilop.cc and
view_tool.cc.
And no changes at all on
view_rip.cc and
view_rip2.cc.
The header file contains
now the class definitions for remHorLin
(view_grol.cc [grol=get
rid of lines]) and anaVertLin
(view_anal.cc). The class
remHorLin shows how the things are now with this Destriping (see also
below) and anaVertLin is a class that provides us with a
"topographical" view on the colors of a single vertical
line.

the line in the middle is the original vertical line from the image. black
is on the top and white on the bottom.
The destriping problem
... apeared to be a really tough problem. I could not find a algorithm to
get rid of all horizontal lines. The one implemented in
view_grol.cc removes many
but not enough. The problem is that it seems that there is no function
which added this lines. As you can see in the picture above, the lines
apear only in the darker regions of the picture and the only rule seems
to be that every third line is darker.
After discussing this with Prof. Pham she said, that these lasts too long
and is not really our problem. She want to get some other pictures and
meanwhile I should continue with the application.
She gave new instructions. We drop ImageVision Library because it is
a commercial library and is not flexible enough and focus now on a image
processing library written in the institute in a previous project.
