The help pages of IPD 8.3-2 seem to be only in Japanese in the IPD_8.3-2.bin.windows.zip 
archive !!!

I modified the file builder_help.sce so online help files are built for three languages 
(German, English and Japanese) and each help file has a different file name.

Hi, Why i cant download this module from ATOMS from Scilab 5.4  thankx in advance

Hi,

I installed IPD 8.3-2 under Scilab 5.3.3 64bit (Windows 7) and got an error message when
the toolbox was to be loaded (some non-descript error from link about a library not being
found). The solution was to install the Visual C++ 2010 Redistributables (available from
Microsoft). Maybe a note about this dependency in the docu would be helpful.

Hi,

I am currently using IPD to perform a blob search on several high resolution picture
(2048x1536). Analysing more than 20-30 out of 500 pictures I ran into memory problems,
which could not be solved by maximizing the stacksize and gstacksize. I also reduced the
color map of all images to 2 colors (similar to im2bw from SIVP) by hand and tried
different formats (png, bmp, jpg and tif). The memory leak was still present.
Using Task Manager and excecuting every line of my program step by step I was able to nail
the memory leak down to the SearchBlobs and AnalyseBlobs function. If one applies this
funtion to the same previously read image matrix the memory consumption of scilab adds up
by approx. 16Mb for each execution (file size is 384kb). 
I was not able to free up the memory allocated by these functions, so Scilab will abort
with an error message pointing to random lines. The memory used at that point is roughly
1Gb.
I am running Scilab 5.3.3 and IPD 8.3.2 and SIVP 0.5.3 on a Windows 7 32bit machine.
I tried to install IPD and SIVP on Scilab 5.4 beta but without success.

Maybe there is a quick and dirty work-around to re-allocate the memory or a bugfix.

Cheers

Hi Lutz,

Due to some changes between 5.3 and 5.4 family, the library LibScilab.dll has disappeared
in the 5.4. This causes a problem to load in a 5.4 the binary files which are compiled on
a 5.3. We have to compile again every module specifically for >= 5.4 for windows. We
are
currently in the process of doing it, but we took advantage of the change to improve our
Atoms compilation chain so that the number of non-loading toolboxes would reduce. IPD is
now available for 5.4, after an atomsSystemUpdate.

@ Harald Galda : I took the liberty to create a new version of your module, based on the
same sources, only to make it available for >= 5.4.
Answer from Lutz Winkelmann -- July 20, 2012, 02:56:49 PM    
Hello Simon, Hello Mr. Galda, 

Thank you for compiling IPD for 5.4. It works great, but it still has the memory leak.
I was able to nail the problem down to SearchBlobs, which constantly fills the memroy and
does not re-allocate the used space anymore. 
Unfortunately I was not able to find the macro or function related to SearchBlobs in the
IPD folder. Is it an external function? Using Scilab 5.4 and IPD 8.3.1-1 I still can't
open and process more than 20 pictures in a row. I tried to clear all unused variables to
free some memory, but it keeps on filling up the memory pretty quickly. 

Further more I found some minor issue in 8.3.1-1 with 5.4, I can't open tif images any
more. That's not of a big deal to me and might be related to the changes in Scilab 5.4.

Thank you for your help and for the great IPD module.
Keep up the good work.

Cheers

Lutz

While trying to extract, the IPD files ask for password. Kindly inform of how to fix this
problem.

Hello,

Are you chosing the 8.3 version because you run Scilab 5.3?
Scilab 5.3 is a very old release. The latest IPD releases for Scilab > 5.3 are
extracted
with no problem and without password.
Downloading and installing and setting a new Scilab release takes 2+3+2 mn.
It does not require uninstalling your current release. It does not require to have
admin rights on your computer: you can install Scilab where you want, even on a USB key.

Hello Mr. Gougeon,

I had to use Scilab 5.3 due to working on a Windows xp pc and its direct availability with
the people in my institution. Now I see that I can upgrade to a maximum of Scilab 5.5.2.
However, I have already written around 50 small scripts for my work and installed SIVP,IPD
and some other toolboxes.

Is it really worth to go for Scilab 5.5.2 in my case? Would it significantly improve the
computation time or some another benefit?

Also, I am facing a problem of function ShowImage (when using my scripts on other
computers, it works fine on my system). It says that there is no more memory for the
function grayplot. After some browsing I think it is a bug.

I already tried to use predef(0) but it didn't free up the memory. Function 'Clear a'
clears even variables in SIVP, IPD and GUI toolboxes and hence the script shows up a lot
of errors. Is there any solution to this problem without creating a lot of functions
myself.

Thanks for the help,
Regards
Akash
