- hi.
can i ask what kind of video clip u use to test your program? is it complex
environment or only one object in the scene to tracked?
thanks.

- Mhhh it seems strange that collapse after some frames...I was thinking to upload a
new version of the video-tracker more improved and with a cleaned up source-code.

- i'm sorry that i didn't notice other issues n i know how to do it now. btw, i use a
video clip to test your program n it collapses after about 125 frames. i don't know
whether i misuse your program or not?

(how to create libblob.lib?) reported by intellyoung
- hello. when building solution, libblob.lib is needed. i use windows
instead of linux, so libblob.a is not useful for me.
can i ask how to create libblob.lib? is it created using cvBlobsLib?
thanks a lot.

- Hi admins, to begin with, sorry i am not rasing an issue and thanks for
your hardwork. I checkout the code from SVN, but i would like to run it. I
searched the whole folder but could not find any video that goes it.
Kindly enlighten me!
THANKS IN ADVANCE!! :)

(Please help me if you make it build on Visual C++) commented on by thomas.zubeli
- I didn't go through all of it before, but it seems that you also have a linking
problem, the exact same, with wxWidgets. You didn't give the linker the good
libraries. Follow the tutorial http://wiki.wxwidgets.org/Microsoft_Visual_C%2B%2B_Guide , especially the "Creating a
New Project by Hand" part.

- It's not a compiling error, it's a linking one!
In Visual C++, go to the "Project" menu -> "Properties" -> "Linker" tab -> "Input"
category -> "Additional Dependencies" and then add "cvblobls.lib" to the possible
libraries already there.
It worked for me, hope it will for you

I tried to build the project by create win32 console from existing code.
But there are a lot errors. I already build the wxWidget and put them in
VC/include
C:\wxWidgets-2.8.9\lib\vc_lib\mswd\
C:\wxWidgets-2.8.9\include
I also copy the cvblobslib.lib to the project folder and use /MDd for

If you could made it build successfully in Visual Studio, please help me
with a zip file of your project or sth... to tua08698@temple.edu.
Your help is very appreciated.

- Ok! Well done. You are welcome. The best of development in linux is that "you
understand what you are doing" because the shell is difficult, but if you keep in
mind what writing, you cannot go wrong. This is the opposite that happens when you
use the IDE and wizard env. Thery are good to use if you have a previous idea of how
works the things "under the hood".

(Error when i use make ) commented on by iacopo.masi
- I explained you why you get this error: the linker system does not find the library
lBlob.
First of all if you set the GCC C++ Linker-->Libraries, you don't have to do twice in
the miscellaneous->-lcxcore -lcv -lhighgui -lBlob -lBlobResult
-lBlobExtraction . So erares the "miscellanesous" string in Eclipse.
Then the library path of opencv is correct /usr/lib, but instead what is the library
path of the other Blob Lib?
Follow me: but the lblob.a file taken from this svn and put it in
/abc/workspace/blobdetection and then fix the Eclipse project like this:
GCC C++ Linker-->Libraries--> cv
highgui
cxcore
blob
Tell me the result, however I suggest you to experience with command line
compiling,linking, static/dyanmic library and the Makefile env. under Linux.
The Eclipse CDT configuration tools is only a GUI to configure the Makefile to
compile the project.

- if the filename of the library is liblob.a try to pass the compier -lblob withouth
the "B", but with "b" in the same case of the filename.
This option can be set in Eclipse Project under C/C++ Linker options when you set
the linking library. So try to erase the string in Eclipse in Miscellaneous.

- The error seems caused by the linker that doesn't load the correct dynamic library
Blob.so one passed throughout -lBlob parameter.
Moreover why do you pass two times the library at the linker?
g++ -L/usr/lib -Xlinker -lcxcore -lcv -lhighgui -lBlob -lBlobResult
-lBlobLibraryConfiguration -lBlobExtraction (first time)-o"blobtracking"
./src/blobtrack.o
-lcv -lBlobExtraction -lBlobLibraryConfiguration -lBlob -lBlobResult -lhighgui
-lcvaux (second time)
change that in :
g++ ./src/blobtrack.o -o blobtracking -L/usr/lib -lcv -lBlobExtraction
-lBlobLibraryConfiguration -lBlob -lBlobResult -lhighgui -lcvaux
In my program I put the libblob.a static library in the same directory of the binary
and then passed the compiler this: -L. -lblob
Where did you pick the Blob library?
