是否可以使用opencv的imshow在不使用工具栏的情况下显示图像？

Question

When OpenCV's imshow is invoked, it always shows a toolbar at the top of the image. Is there anyway to turn it off?

Mat frame;
bool bSuccess = cap.read(frame);
imshow("MyVideo", frame);
if ( cvWaitKey(30) == 27 ) {
       break;
}

I'm using OpenCV 3.0 under ubuntu 14.04.

Answer 1

You can put namedWindow("MyVideo", CV_GUI_NORMAL); outside of the loop containing imshow("MyVideo",frame); .
