图像加载以及融合

图像加载函数

int base::loadImg( Mat &mat, QLabel* labelImage )
{
    cvtColor(mat, mat, CV_BGR2RGB);

    QImage::Format  imgFormat = (mat.channels() == 3) ? QImage::Format_RGB888:QImage::Format_Indexed8;

    QImage image((const uchar*)(mat.data), mat.cols, mat.rows, mat.cols*mat.channels(), imgFormat);

    labelImage->setPixmap(QPixmap::fromImage(image));  
    labelImage->resize(labelImage->pixmap()->size());

    return 0;
}

图像的线性融合

int base::mixImg( string strFilePath, string strTempFilePath, QLabel* labelImage)
{
    Mat matSource = imread(strFilePath);
    if (!matSource.data)
    {
        return(-1);
    }

    Mat matTemp = imread(strTempFilePath);
    if (!matTemp.data)
    {
        return(-1);
    }

    Mat roi = matSource(Rect(0, 0, matTemp.cols, matTemp.rows));

    //g(x) = af(x) + (1-a)f(y) + m
    addWeighted(roi, 0.9, matTemp, 0.1, 0.0, roi);

    
    loadImg(matSource, labelImage);
}
