How to use OpenCv utilities in Command prompt

Question

I am doing object detection in images using OpenCv library in Java Eclipse. I am using Cascade Classifier Training for this using Haar features.

For training the classifier I need to generate some text files, .vec file and finally .xml file on command prompt. I have already generated text files but while making .vec file using opencv_createsamples utility on command prompt, I am getting error:

opencv_createsamples command is not recognized.

To resolve this I need to build opencv with TBB Threading Building using CMake. I am unable to do this. Please anyone suggest me the full and proper method of building opencv with TBB using Cmake.

Thanks in advance.

That blog describes building OpenCV with TBB enabled(WITH_TBB=ON) on Ubuntu 14.04: rodrigoberriel.com/2014/10/… – Kiss

Make sure you have the right file name by doing a search in explorer. then add the address prefix. Notice that this example has a d for debug.

C:\opencv\bin\Debug\opencv_createsamplesd.exe -vec samples.vec
