hello,

i have decided to try and train my own haar database of some object and in my old opencv (changelog says OpenCV 1.0, October 18, 2006) i had a file called bin/createsamples.exe.

also, everyone online is referencing to file bin/opencv_createsamples.exe.

however, in the latest build that i've downloaded i can find no such thing. i can only find uncompiled .h and .cpp files under the apps directory.

have the pre-built excutables been removed from the latest opencv builds or did i download something wrong?

please excuse this nooby question

edit: this is terrible. with the hassle, i've been trying to compile the haar training files for an hour an half now. the includes are even wrong: the new version of opencv has no "highgui.h", or "cxcore.h" in main directory. they are now located in "opencv/highgui.h", etc. which is funny, because the same files including stuff just like "highgui.h" are also including "opencv2/core/core.hpp". meaning that they should be including "opencv/cxcore.h" instead of just "cxcore.h".

those files need cleaning

edit2: oh god, i am giving up. now there is another barrier- microsoft visual studio has a bug that makes incremental linking unfunctional. however, i can't compile the haar training cpp files without incremental linking. i am going to use the old exe from the old opencv from 2006

have there been any changes to the haar training files?

Hi,

I am using visual studio 2010 too, and didn't face any problem in compiling these files. I think you have not added one/some of the following paths to project:

  • C/C++ -> Additional Include Directories
  • Linker ->General: Additional Library Directories
  • Linker->Input: AdditionalDependencies

You can also add "opencv" directory to paths instead of changing things like "highgui.h" to "opencv/highgui.h" in code files.

After setting these, I am successfully able to build/execute all files like createsamples.cpp, haartraining.cpp etc.

no, i have every ilbrary added, i have already built a single opencv project- my own program. the problem with the haartraining cpp files is that there are multiple files at once. if i add them into a single project file- they have multiple main() functions- which of course results in conflict. if i add a single .cpp file into each separate project file- i get a linker error: 1>LINK : fatal error LNK1123: failure during conversion to COFF: file invalid or corrupt . google says that this is a microsoft visual studio 2010 bug and i should either disable incremental linking or install VS service pack. now, if i disable incremental linking the .cpp file won't compile, as it needs to link other files from other files. and installing a whole servicepack just for this project is an overkill.

Well, for sure we need to add only one file (say haartraining.cpp) to the project. I am doing the same and am able to use it.

that's because you have the visual studio 2010 version that doesn't include the linker error bug

Ok..that might be the case then. I have not tried with different versions of visual studio.
