1. 创建控制台工程，工程文件如下，

QT -= gui

CONFIG += c++11 console

CONFIG -= app_bundle

# The following define makes your compiler emit warnings if you use

# any Qt feature that has been marked deprecated (the exact warnings

# depend on your compiler). Please consult the documentation of the

# deprecated API in order to know how to port your code away from it.

DEFINES += QT_DEPRECATED_WARNINGS

# You can also make your code fail to compile if it uses deprecated APIs.

# In order to do so, uncomment the following line.

# You can also select to disable deprecated APIs only up to a certain version of Qt.

#DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x060000    # disables all the APIs deprecated before Qt 6.0.0

SOURCES += \

        main.cpp

# Default rules for deployment.

qnx: target.path = /tmp/$${TARGET}/bin

else: unix:!android: target.path = /opt/$${TARGET}/bin

!isEmpty(target.path): INSTALLS += target

INCLUDEPATH += C:\opencv\build\include

QMAKE_LIBDIR  += "C:/opencv/build/x64/vc15/lib"

win32:LIBS    += "C:/opencv/build/x64/vc15/lib/opencv_world453d.lib" \

              "C:/opencv/build/x64/vc15/lib/opencv_world453.lib"

2. 主程序

#include <QCoreApplication>

#include "opencv2/imgproc/imgproc.hpp"

#include "opencv2/core/core.hpp"

#if (CV_MAJOR_VERSION >= 3)

    #include "opencv2/videoio/videoio.hpp"

#endif

#include <opencv2/opencv.hpp>

using namespace cv;

using namespace std;

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

{

    QCoreApplication a(argc, argv);

    //stage1 source input

    Mat srcImage = imread("1.jpg");

    imshow("Source", srcImage);

    //stage2 blur process

    Mat dstImage;

    blur(srcImage,dstImage,Size(7,7));

    //stage3 Gauss process

    Mat outImage;

    GaussianBlur( dstImage, outImage, Size( 5, 5 ), 0, 0 );

    //stage4 output to show

    imshow("blur_gauss", outImage);

    return a.exec();

}
