QString str;
str.setNum(src1->width);
ui->lineEdit->setText(str);
str.setNum(src1->height);
ui->lineEdit_2->setText(str);
str.setNum(src2->width);
ui->lineEdit_3->setText(str);
str.setNum(src2->height);
ui->lineEdit_4->setText(str);
}
Widget::~Widget()
{

cvReleaseImage(&src1);
cvReleaseImage(&src2);
cvReleaseImage(&dst);
cvDestroyAllWindows();
}
void Widget::on_pushButton_clicked()
{
bool ok;
double alpha,beta,temp;
int x,y,width,height;
temp = ui->lineEdit_7->text().toDouble(&ok);
if (ok)
{
alpha = temp;
}
else
{
alpha = 0.4;
}
cout << alpha << endl;
temp = ui->lineEdit_8->text().toDouble(&ok);
if (ok)
{

}
else
{
beta = 0.6;
}
cout << beta << endl;
x= ui->lineEdit_5->text().toInt(&ok,10);
cout << x << endl;
y = ui->lineEdit_6->text().toInt(&ok,10);
cout << y << endl;

cout << height << endl;
cvSetImageROI(src1,cvRect(x,y,width,height));
cvSetImageROI(src2,cvRect(x,y,width,height));
cvSetImageROI(dst,cvRect(x,y,width,height));
cvAddWeighted(src1,alpha,src2,beta,0.0,dst);
cvResetImageROI(src1);
cvResetImageROI(src2);
cvResetImageROI(dst);
cvShowImage("jdh1",src1);
cvShowImage("jdh2",src2);

}
