[solved]using inpaint of opencv in qt

[bts-007]

I am using inpaint from opencv. I am getting an output when I compile it with g++(i.e g++ impaint.c pkg-config opencv --cflags --libs). I have planned it use in qt. I am getting an error message

undefined reference to 'cv::inpaint(cv::_InputArray const&, cv::_InputArray const&, cv::_OutputArray const&, double, int)'

main.cpp
@

#include <iostream>
#include <opencv2/opencv.hpp>
#include <opencv2/photo/photo.hpp>
#include<QApplication>

int main(int argc,char *argv[])
{
QApplication app(argc,argv);

//Our color image
cv::Mat imageMat = cv::imread("cat.jpg", CV_LOAD_IMAGE_COLOR);

//Grayscale matrix
cv::Mat grayscaleMat (imageMat.size(), CV_8U);

//Convert BGR to Gray
cv::cvtColor( imageMat, grayscaleMat, CV_BGR2GRAY );

//Binary image
cv::Mat binaryMat(grayscaleMat.size(), grayscaleMat.type());

//Apply thresholding
cv::threshold(grayscaleMat, binaryMat, 180, 255, cv::THRESH_BINARY);

//Show the results
cv::namedWindow("original", cv::WINDOW_AUTOSIZE);
cv::imshow("original", imageMat);

cv::namedWindow("Output", cv::WINDOW_AUTOSIZE);
cv::imshow("Output", binaryMat);

cv::Mat dst;
cv::inpaint(imageMat, binaryMat, dst, 1, cv::INPAINT_TELEA);

cv::namedWindow("result", cv::WINDOW_AUTOSIZE);
cv::imshow("result", dst);

return app.exec();

}

Hi,
Ain't the cv::inpaint() function in opencv_photo, about the only lib you did not include in your project file?

Hi,

You can use pkg-config with qmake
IIRC:
@
CONFIG += link_pkgconfig
PKGCONFIG += opencv

If you are on windows and using the g++ come with Qt, you need to recompile the openCV by yourself.
