News from Harald Galda -- October 6, 2016, 01:38:23 PM

I tried to download and compile the third party library OpenCV on a virtual PC
with 64 bit Ubuntu Linux as described at

http://docs.opencv.org/3.0-last-rst/doc/tutorials/introduction/linux_install/linux_install.html

When I tried to download the required packages, I received an error message.
When I compiled the toolbox, some binary files were created, but I received some
error messages.

I was able to build and to load the toolbox on Linux. But an error message
occurs when calling ReadImage. The internal function ReadImageFile should return
two outputs: The first is a list of gray values or channel intensity values. The
second specifies the number of rows, columns and color channels. However, the
path of the image is returned instead.

This means that the library function for loading an image does not work properly
on the virtual Linux machine.  An image processing toolbox that has no
functionality for reading image file is not of much use. Therefore, I am not
going to upload the 64 bit Linux binaries. I need no virtual 32 bit Linux
machine so I am not going to attempt to build the toolbox for 32 bit Linux.

I suggest that someone who has enough Linux experience build the toolbox on
Linux.

News from Harald Galda -- November 18, 2014, 10:46:47 PM

The toolbox is available on MacOS Yosemite now. Distance transform and watershed
transform are not included due to problems with external library functions the
distance transform depends on. I suggest that the sources of the toolbox and
OpenCV are built on MacOS and a workaround for the crash in
DistanceTransform.cpp is found later.

The packages generated by ATOMS compilation chain on 10 october 2011 work fine.

News from Harald Galda -- October 7, 2011, 07:36:17 PM

The 64 bit Windows package uploaded on 2011-10-07 09:36:44 does not contain
online help. The sources uploaded on 2011-10-07 19:25:13 do contain the online
help.

The 32 bit Windows package uploaded on 2011-10-07 09:50:00 has no build log file
and can not be downloaded. It seems that the ZIP file contains an error. I
disabled both ZIP files. The 32 bit Windows package is replaced by a version I
built. I downloaded the 64 bit Windows package built by ATOMS compilation chain,
I manually added help files and I uploaded it.

I suggest that the toolbox is re-built on 32 bit Windows and 64 bit Windows.

News from Harald Galda -- March 8, 2011, 07:52:06 PM

A package for 32 bit Linux was built. However, it seems that the Linux version
will not work because the sources I submitted do not contain the Linux version
of OpenCV. 

I suggest the following steps to make the toolbox available for Linux:

1. A subdirectory should be added to sci_gateway/cpp/lib/

2. The following files should be copied to the new subdirectory: cxcore210.lib,
cxcore210.so, cv210.lib, cv210.so, highgui210.lib, highgui210.so

3. The script builder_gateway_cpp.sce in the directory sci_gateway/cpp/ should
be extended so the library path is found and the *.so files are copied to the
cpp directory.

Please understand that I am not able to do this as I do not have access to a
Linux machine.

IPD 8.0 was uploaded on February 21st, 2011. This is the first version that can
be built on 64 bit Windows. The toolbox can be built on 32 bit Windows, too, of
course.

As online help can not be built on Scilab 5.3.0, the help files of IPD 7.0 are
provided in the source files and building help is disabled on Scilab 5.3.0.

News from Harald Galda -- December 30, 2010, 10:56:19 AM

Building the online help does not work with Scilab 5.3.0. If you intend to build
the sources, please comment the line

    tbx_builder_help(ToolboxPath);

in line 60 of builder.sce and type

    tbx_builder_help('C:Programs\scilab-5.3.0\contrib\IPD\7.0\') 
    // if installed via ATOMS

or

    tbx_builder_help('C:\Programs\scilab-5.3.0\contrib\IPD-7.0\')
    // if installed manually

in a previous version of Scilab.

Version 6.1 was added. The differences between versions 6.1 and 6.0:

- Online help will always be loaded when loading the toolbox, 
  regardless of installation method.

- Image paths in online help examples now consist of the dynamically
  determined toolbox path and the subdirectory 'demos'. This makes 
  ist sure that examples can be executed in Scilab, regardless of the
  directory structure.

News from Harald Galda -- September 8, 2010, 02:54:05 PM

The toolbox should be re-built by atoms compilation chain, because IPD.Start had
to be be modified.

The following lines were replaced:

// load help

help_path = pathconvert(IPD_PATH) + 'help' + filesep();

select getlanguage()
  
 case 'de_DE'
   
  help_path = help_path + 'de_DE';
  
 case 'en_US'
   
  help_path = help_path + 'en_US'; 
     
 case 'ja_JP'
   
  help_path = help_path + 'ja_JP';
  
 else  
   
  help_path = help_path + 'en_US';
      
end;
    
if isdir(help_path) then
 
 current_path = pwd();
 
 chdir(help_path);
 
 exec('addchapter.sce');
 
 chdir(current_path);
 
end


by the following code:


// load help

help_path = pathconvert(IPD_PATH) + 'jar' + filesep();

if isdir(help_path) then
 
 add_help_chapter('IPD - Image Processing Design', help_path, %F);

IPD 6.0 was released on 5 September 2010. There are the following changes
between versions 6.0 and 5.0:

1. Template matching functionality was added.
2. This version can be built using Scilab 5.3.0 Beta 3.

News from Harald Galda -- July 12, 2010, 09:07:23 AM

I tested IPD 5.0 on Scilab 5.2.2 and Windows 7. I built the sources using the
local version of Visual Studio. IPD 5.0 can be loaded into Scilab 5.2.2. The
demos work.

News from Harald Galda -- April 20, 2010, 11:24:54 AM

The C++ compiler the OpenCV libraries were built with must be present on the
machine IPD is loaded. If an error message such as "cxcore200.dll does not
exist" occures when loading IPD into Scilab, there are the following options:

1. Install Microsoft Visual Studio 2008 Express Edition on your computer.

2. Download OpenCV 2.0 and build it with the C++ compiler installed on your
computer. Then replace the files

    cxcore200.dll
    cv200.dll
    highgui200.dll

in the directory 

   contrib\IPD-5.0\sci_gateway\cpp\

and the files

   cxcore200.lib
   cv200.lib
   highgui200.lib

in the directory

   contrib\IPD-5.0\sci_gateway\cpp\

by the corresponding files created by your C++ compiler.

Please run the script

   builder.sce

in the directory

   contrib\IPD-5.0\

then.

Version 5.0 was released on 26 March 2010. The differences between version 4.0
and 5.0 are the following:

- Functions for computing wavelet frames (similar to discrete wavelet 
  transform, but invariant to translation) were added.

- Constants implemented as variables such as TYPE_DOUBLE, EDGE_SOBEL are
  global variables now so the toolbox can be loaded by atomsLoad.

- The stack size is increased to maximum when the toolbox is loaded.

News from Harald Galda -- March 17, 2010, 05:25:15 PM

IPD 4.0 was released on 16 March. 

New or changed functions:

1. CalculateTextureEnergy, can be used for texture segmentation

2. EdgeFilter re-implemented as *.sci file so edge filters can be modified

3. Linear filtering with rectangularand separable filters.

Building the toolbox: 

The source package contains the *.lib and *.dll files of OpenCV so that the
source package can be compiled on Windows. If you intend to compile the package
on Linux or Mac, please replace the *.lib and *.dll files by the corresponding
files of your operating system.

Online help:

A German and a Japanese online help are added. If you find errors in the
Japanese help, please tell me. Please feel free to write in Japanese in this
case.

News from Harald Galda -- March 4, 2010, 02:47:20 PM

The toolbox can be downloaded with Atoms GUI now. Atoms creates the directory 

scilab-5.2.0\contrib\IPD\
scilab-5.2.1\contrib\IPD\

with the sub-directory

scilab-5.2.0\contrib\IPD\IPD-3.3\
scilab-5.2.1\contrib\IPD\IPD-3.3\

When you copy or move this sub-directory

to

scilab-5.2.0\contrib\
scilab-5.2.1\contrib\

so that there is the directory

scilab-5.2.0\contrib\IPD-3.3\
scilab-5.2.1\contrib\IPD-3.3\

the toolbox can be loaded into Scilab after closing and relaunching it. 

There is an error message "installation failed", but this is related to some
internal problem of Atoms.

Hi Dr Harald, 

Thank you again for your contribution. I've been posting some matlab base image 
processing example at http://basic-eng.blogspot.com/, and was trying to
port over to 
scilab last time with sip and svip. 

I believe with your contribution, I could convert even more code to scilab base. I hope 
you don't mind if I quoted you name (and your tools) in my blog ragarding image 
processing using scilab?

Thanks.

Regards,
Chin Luh

I used this example with newest sci-lab and IPD module loaded via mnodule menager.

Image = 0.5 * ones(9, 9) // generate gray image
Image(:, 3) = 0 // draw dark line
Image(:, 7) = 1 // draw light line
StructureElement = CreateStructureElement('square', 3) // generate structuring element
ResultImage = ErodeImage(Image, StructureElement)

There is stil problem with:

-->StructureElement = CreateStructureElement('square', 3) // generate structuring element
 !--error 4 
Undefined variable: TYPE_STRING

How can I fixed it?

I loaded the IPD-3.3 into Scilab 5.2.1 and I did not reproduce that error.

The variable

     TYPE_STRING

is defined in

     IPD-3.3\etc\IPD.start

and IPD.start is loaded into Scilab by

     IPD-3.3\loader.sce

Does that error occur only once (then it is temporary) or more than once?

I am also experiencing such issues with IPD 3.3 installed thank to the ATOMS interface:

-->rgb=ReadImage("dispersion_spectrale.png");
 !--error 4 
Undefined variable: TYPE_STRING
at line      30 of function ReadImage called by :  
rgb=ReadImage("dispersion_spectrale.png");

--> TYPE_STRING=type("a"); 
--> rgb=ReadImage("dispersion_spectrale.png");
--> [image tmp]=RGB2Ind(rgb);
 !--error 4 
Undefined variable: TYPE_DOUBLE
at line      53 of function RGB2Ind called by :  
[image tmp]=RGB2Ind(rgb);
--> // ------------------------------------------------
--> TYPE_DOUBLE=type(1.1); [image tmp]=RGB2Ind(rgb);
-->ShowImage(image,"Image test")
 !--error 4 
Undefined variable: TYPE_INT

ShowImage(image,"Image test")
--> // ------------------------------------------------

 !--error 4 
Undefined variable: TYPE_BOOLEAN

at line     116 of function ShowImage called by :  
ShowImage(image,"Image test")
--> // =======================================================
Apparently, either IPD\3.3\loader.sce launching IPD.start initializing these variables is
not run when installing IPD through the ATOMS manager, or it is run but from a function in
which variables are defined locally and lost at the end of it. Or... ?

Answer from Harald Galda

-- March 18, 2010, 01:45:26 PM

The variables TYPE_STRING, TYPE_INT, EDGE_SOBEL etc. are defined inside IPD.start and
IPD.start is called by loader.sce. Maybe loader.sce is not called after installation by
atomsInstall. 

As far as I know a toolbox is not loaded during the Scilab session in which it was
installed by atomsInstall. A toolbox is loaded after closing and re-starting Scilab.

loader.sce is called in a function (atomsLoad) so variables that are defined in this file
are not known from the console scope. You've to use global variables.

You can do it in the same Scilab session:
--> atomsInstall IPD
--> atomsLoad IPD
