Scilab Image and Video Processing toolbox

Comment from Rober Perret -- May 1, 2010, 09:12:15 PM    

hola acabo de instalar SCILAB-5.2.2 y quise instalar el paquete  SIVP, a traves de scilab
pero al reiniciar scilab me aparece:
 "Start SIVP - Scilab Image and Video Processing Toolbox
 
 Package opencv was not found in the pkg-config search path.   
ADVERTENCIA: OpenCV (version >= 1.0.0) is needed for loading SIVP"

que puedo hacer? 
Estoy usando fedora 12 86_64
Desde ya muchas gracias

It does not work on Ubuntu 10.04 "Lucid". Opencv is installed. The package libcv4 installs
libcxcore.so.4, but not libcxcore.so.1. I tried to symlink libcxcore.so.1 to so.4, but it
did not solve the problem:

Startup execution:
  loading initial environment

Start SIVP - Scilab Image and Video Processing Toolbox
	Load macros
	Load gateways
atomsLoad: An error occurred while loading 'SIVP-0.5.1':
	addinter: The shared archive was not loaded: libcxcore.so.1: cannot open shared object
file: No such file or directory

I've tried and success to install SIVP on Ubuntu 10.04 "Lucid". Maybe this link is useful

I believe you should ship the dependencies into your ATOMS package.
Otherwise, the user will need to have the same version as the compilation chain...

I have the same problem Rober, which for those who do not speak spanish is having trouble
using this toolbox. 
After spending two days trying to run python with opencv in my UBUNTU computer, i tried to
give it a go to scilab + sivp. I have the same problem. What is even more funny is that
when I go to the menu bar "toolboxes" (I think, i use the french version), and click on
SVIP, I get:

SIVP - Scilab Image and Video Processing Toolbox 0.5.0
Bibliothèque partagée chargée.
Edition de liens effectuée.

Which in English means, everything is ok, expect that it reads 0.5.0 and not 0.5.1 as when
I look at Applications menu.

However, the main issue is that none of the commands of the toolbox work. Any ideas?

Thanks in advance.

Also, if anybody knows how to check if opencv was compiled with the ffmpeg flag on, as I
installed from synaptic.

For everyone who encountered:

"addinter: The shared archive was not loaded: libcxcore.so.1: cannot open shared object"


I was able to run SIVP successfully after creating symbolic links between the opencv
libraries in my machine and the versions needed by SIVP. Here are the steps:

1. Installed SIVP using ATOMS (from Scilab)
2. Installed opencv (yum install on fedora should be fine). (Please note: To enable video
support, you might need to compile and install opencv from source) 
2. Updated the PKG_CONFIG_PATH in my bash profile to point to opencv libraries (in my
machine /usr/lib64
3. Symlinked the libraries: libcxcore.so.1 with libcxcore.so.2 (on my machine) There are a
few other opencv libraries that need to be symlinked. You should know which ones after
performing this step and launching Scilab.  

Hope this will be of help...

OpenCV detection does not work properly on Fedora because rpm does not provide .pc
configuration file. So to make it work on Fedora 13/14 (64bit) you need to remove lines
32-38 from 'scilab-5.2.2/share/scilab/contrib/SIVP/0.5.1/etc/SIVP.start', then in
'scilab-5.2.2/lib/thirdparty/' you need to create these symbolic links:
ln -s /usr/lib64/libcv.so.2.1.0 libcv.so.1
ln -s /usr/lib64/libcvaux.so.2.1.0 libcvaux.so.1
ln -s /usr/lib64/libcxcore.so.2.1.0 libcxcore.so.1
ln -s /usr/lib64/libhighgui.so.2.1.0 libhighgui.so.1
ln -s /usr/lib64/libml.so.2.1.0 libml.so.1

SIVP embedded opencv 2 (VS 2008 build)
I suppose that there is a runtime trouble between VS 2008 and VS 2010

Please check that you have VS 2010 runtime or uninstall OpenCV-2.2.0-win32-vs2010.exe

Have you do some others modifications ?

Why do not use ATOMS package ?
