Scilab Image and Video Processing toolbox

Comment from Joao Ferreira -- March 18, 2012, 11:31:53 AM    

It doesn't work in Fedora 16 (64 bits), the scilab reports the file libsivp.so is missing.

I saw a recent post on OpenCV mailing list the other day. There is a maximum bandwidth on
USB, so you might have to access extra cameras through other means. That may be your
problem.

Having a problem with loading the toolbox on Scilab 5.4.0, on Win7.
Keep getting the error
"
addinter: The shared archive was not loaded: A dynamic link library (DLL) initialization 
routine failed.
"
although the installation process went fine with no errors.
Any suggestions?

Same for me.

It would be nice in SIVP.start to load the help chapter _before_ the gateway.
Actually, this would allow to view help pages even when the gateway has not been loaded
(what is by far more frequent than for the help).

It would be better to have image rotation function "i.e imrotate(im)" and
function for getting pixel coordinate from image"i.e xgetpixel(im)". 

Thank you :)

Could not load this package on Ubuntu 32 bits, neither by atoms install, nor by manually
building and loading. OpenCv is installed.

atomsLoad: An error occurred while loading 'SIVP-0.5.3.1-2':

such file or directory

I was trying to preview a USB 2.0 Webcam using the SciLab Demonstration button/menu in the

command window.  Under SIVP I used the "Grab frames from a camera" and go through
the GUI 
pop up and I see my camera it displays.  However when I do this all I get is a black screen

that doesn't appear when I use any other software to preview through the same camera. 

Any ideas???

Hi,

Your toolbox is extremely interesting, and we thought of using it for video processing. 
To test it, I installed SIVP on Scilab 5.4.1, copied the lena.png file into a directory 
where I have write rights and tried :

-->im = imread('lena.png');
-->n = avifile('lena.avi', [300;300], 30);
                                       !--error 999 
avifile: Can not create video file lena.avi.

As far as I understand, it seems that I need to compile the SIVP toolbox from the sources 
along with the Opencv lib. Am I right ?

If this is true, that's too bad, since this is the whole purpose of an atoms module to 
provide out-of-the-box binary releases in working condition. Is there a release which is 
planned with pre-built Opencv binaries included ?

Regards,

Micha?l

Hello,



I need to install the SIVP tool box.



Unfortunately, when trying to load 
http://atoms.scilab.org/toolboxes/SIVP/0.5.3.1/files/SIVP_0.5.3.1-2.bin.x64.windows.zip

 from atoms, i have a checksum error, and the installation fails:







atomsDownload : Le fichier t?l?charg? ne v?rifie pas la signature MD5SUM :

	 - fichier : 'C:\Users\F214053\AppData\Roaming\Scilab\scilab-5.4.1\atoms\x64
\SIVP\SIVP_0.5.3.1-2.bin.x64.windows.zip'

	 - MD5SUM attendue : '742cca6cd8ab0391e6def0fe4760b7b9'

	 - MD5SUM consult?e : 'f0b9f08c33ccb19ff3d633f2c74b8426'



Do you have a suggestion to solve the problem?



I have scilab 5.4.1 64 bits Under Windows 7 



Please note that on my previous computer,  (Windows xp 64) with scilab 5.4.0, i had no pb 
to load the same version of SIVP.







Thank you very much.



Best regards
