OPENCV 2.1 QT CREATOR INTEGRATION

Assuming u downloaded this setup 
and installed it successfully 
"OpenCV-2.1.0-win32-vs2008.exe" 

Let us assume for now that the installation directory is "C:\OpenCV2.1" 

To make ur current qt project or a new project "opencv" compatible :| 
here are the modifications or rather additions which are to be made to ur 
.pro file 

# INCLUDING HEADER PATHS AND LIBRARIES AND THEIR PATHS###

INCLUDEPATH +="C:\OpenCV2.1\include/opencv"

LIBS += -L"C:\OpenCV2.1/lib"

LIBS += -lcv210 -lcxcore210 -lhighgui210 -lcvaux210 -lcxts210 -lml210 -lopencv_ffmpeg210

# END OF HEADER INCLUDES AND LIB INCLUDES ### 


so, a sample complete .pro file would look like this.... 

#-------------------------------------------------

#

# Project created by QtCreator 2010-09-21T15:20:29

#

#-------------------------------------------------

QT       += core

QT       -= gui

INCLUDEPATH   +="C:\OpenCV2.1\include/opencv"

LIBS += -L"C:\OpenCV2.1/lib"

LIBS += -lcv210 -lcxcore210 -lhighgui210 -lcvaux210 -lcxts210 -lml210 -lopencv_ffmpeg210

TARGET = opencvTest

CONFIG   += console

CONFIG   -= app_bundle

TEMPLATE = app

SOURCES += main.cpp

heres a sample program as well to help u with it







##dont forget to include QDir,QDebug as well to ur existing app

## along with its existing defaults i.e. QCoreApplication if its  a console app

## etc....etc....

#include "cv.h"

#include "cxcore.h"

#include "highgui.h"

#include "stdio.h"



int main(int argc, char *argv[])

{     QCoreApplication a(argc, argv);

   IplImage* test=cvLoadImage("test.jpg",1);

    cvNamedWindow("test",CV_WINDOW_AUTOSIZE);      cvShowImage("test",test);

    float i=32.45;

   char* temp="amar";

   qDebug() <<   QDir::currentPath() << i <<temp;

    return a.exec();

}

a sample project will be added soon
