Setup of OpenCV 2.4.9

[eldk]

Hello,

I've check and modify an old script to build and install OpenCV-2.4.9:

http://askubuntu.com/questions/346264/does-the-version-of-opencv-shipped-with-12-04-support-v4l2

The modify script for openCV 2.4.9 on ubuntu 12.04 :

1 - create an empty folder in you home directory
2 - create the script in the empty folder and make it executable
3 - launch it with ./nameofscript.sh


#####Begin of script
arch=$(uname -m)
if [ "$arch" == "i686" -o "$arch" == "i386" -o "$arch" == "i486" -o
"$arch" == "i586" ]; then
flag=1
else
flag=0
fi
echo "Installing OpenCV 2.4.9"
mkdir OpenCV
cd OpenCV
echo "Removing any pre-installed ffmpeg and x264"
sudo apt-get -y remove ffmpeg x264 libx264-dev

cd build

I have check it with TAR and repository digikam 4.1.0 : no trouble.
(except for SSE3, I work with a pentium M - see comments in script)

If you use kubuntu-backport, you will have to remove OpenCV 2.4.5
packages before compiling digikam 4.1.0.

If you want tu use internal libpgf, you have to uninstall libpgf package
too, before compiling digikam.

Greatings,

Eric

When you said, no trouble do you tried to use all options from Face Management ?

Because a wrong setup of OpenCV can introduce crashes here. I just
experienced a lots this situation with Windows installer, where i
reduced OpenCV to minimal setup.

In fact after to lost few days with this library, i can said that
OpenCV is a big puzzle with a bad architecture. A wrong option can
have a weird effect at run-time.

So, packagers, please TAKE A CARE.

I currently try to identify which OpenCV component is mandatory to run
face management algorithms safety. It's long and fastidious : OpenCV
has around 30 components optional at compilation time. It's really a
mess.

Hello,

I haven't check facemanagement yet, I was meaning : I should install
digikam 4.1.0 (And just finish with 4.2.0) without warnings on openCV.

I will check facemanagement in next days and weeks.

I've done this because I'm currently working with Digikam 3.5.0 and
notice a huge use of database (mysql) as soon as I start digikam : a lot
of thread are permanents one (I optimise Mysql for other purpose). So
yesterday I decide to check if it was the same with more recent version
of digikam and have the alert message on OpenCV version when build
digikam.

Greatings,

Eric

In that case, is it possible to completely eliminate the dependency on
OpenCV (and losing the face management algorithms, of course)?

For me personally, the face recognition is not important, so if I can get a
more stable Digikam without it, that would be nice.

no. It's too complicated i think. I know that an entry exist in
bugzilla about this topic, but MArcel (other lead digiKam developer)
is not favorable to drop Face Management feature using optional
compilation.

After all, as it's said, if there are crashes, there are only located
to Face Management tool. Do use it...

But as i said previouly, now i know the source of the problem.

- It's a packaging problem.
- It's an UPSTREAM dysfunction fully relevant of OpenCV library.

See my story in this bugzilla comment :

https://bugs.kde.org/show_bug.cgi?id=336650#c3

This problem must be urgently reported to OpenCV team, and problem
must be fixed...

I also fixed a lots of code into libkface to obtain a more robust Face
management background interface for KDE. libkface is the shared lib
used by digiKam to play with face management and all OpenCV API are
called in this library.

So, i can said that future will be really more stable about Face Management...
