Hello NG,

I'm looking for a function that reads an image (.jpg or .bmp) into a 
matrice (similar to Matlab function Imread) . I work with scilab 5.1.1 / 
Win (Vista or XP).

My aim is: I want to read a scanned diagram (curve) and determine the 
corresponding numerical values of the curve.

I already read about the SIP toolbox (Windows version) but most comments 
dealed with older versions of scilab or reported of failures.

As I'm new to scilab I would appreciated if anyone would advise me or 
report about his experiences.


Thanks in advance for any helpful answers.


Regards

Dietmar

That's right. There are no longer available online binaries of SIP
for
Scilab > 4.1.2 on WinXP, and personnal tentatives of rebuilding it
with a C compiler have failed.

I have succeeded in building SIVP (builder.sce. C compiler needed)
for Scilab 5.1.1 on winXP. Then, it works. But i have failed to do so
for
Scilab master > 5.1.1 (while many big improvements of Scilab
have been developped since last April's 5.1.1 release, for the
pending 5.2 release). This is clearly a big drawback: No longer
available image processing tool for Scilab >=5.2 on winXP.

Is there anyone else on the newsgroup having succeeded with SIVP
on winXP / Scilab > 5.1.1 ? Other comments are welcome.

Regards
Samuel

The SIP website advertises that SIP 0.4.0 is supposed to work with 
Scilab 5.1. See right column at:

http://siptoolbox.sourceforge.net/

The corresponding binary file for Windows can be found at:

https://sourceforge.net/projects/siptoolbox/files/

(see file sip-0.4.0-bin-win32-sci4.0-beta.exe under SIP 0.4.0-candidate 1)

I did not try this build but I would be interested by your feedback.

Indeed, SIP having been stalled for several years I had turned to 
SIVP. Now the situation seems to be the opposite: SIP has new binaries 
but SIVP authors seem to have fallen off the face of the earth 
(checked in their forum at SourceForge, and in their bug tracking 
system, latest news is > 1 year old, and so on).

Lack of durability (i.e. long term support) of such software is a 
pain, but you cannot expect it when using a toolbox developed by 
students that sooner or later are no longer students. If SIP is now 
leading again I'll have to return back to SIP and leave SIVP.

But I'll first see which one is working under Scicoslab before making 
my decision. Anyone has experience in using SIP or SIVP under 
Scicoslab perhaps?

What was the problem, and how did you try to build it (which compiler, 
for instance)? (this is just for my education, I'll not dig into this 
problem).

The compiler: Microsoft Visual Studio 9.0
Hereafter is the output from exec builder.sce, up to the error:

This does not look like the output of SIVP-0.5.0. In the latter the 
builder.sce is just a dummy file so that the entry shows up in the 
toolboxes menu. What version of SIVP did you try? Why not the latest?


On the other hand I have checked that SIVP-0.5.0 runs with 
Scicoslab-4.3, at least on Windows. There is a little issue because 
getversion() does not return the same kind of things in Scilab-5 and 
in Scicoslab. Just a slight change to do to make it run:

-->cd SCI/contrib/SIVP-0.5.0
  ans  =

  C:\PROGRA~1\SCICOS~2\contrib\SIVP-0.5.0

-->scipad loader.sce

Then, comment lines 36 and 37 that read:
   scilab_version=getversion();
   scilab_version=str2code( part(scilab_version, 8));
and add:
   scilab_version=4

Save and exit.

Then in Scicoslab, issue:

-->exec loader.sce


That's all. SIVP-0.5.0 seems to be ready to work with Scicoslab-4.3.

First try:

-->cd demos;
  ans  =

  C:\PROGRA~1\SCICOS~2\contrib\SIVP-0.5.0\demos

-->exec canny.sce;

This works for me.

The problem is that SIVP-0.5.0 is very unstable, and most of the demos 
crash:
   face.sce crash on detectfaces()
   noise.sce crash on imshow()
and so on.

I have no time to investigate now on this, unfortunately.
