Unavailable synchronous data
-
Dear All,
I have OpenCV image, get the image data from the Queue.IplImage *opcvImg = cvCreateImage(cvSize(col_size, row_size), IPL_DEPTH_8U,1);
opcvImg = ImageQueue::getQueue();
Upto here, in the watch window I can see that opcvImg has all information.But when I convert the IplImage* to cv::Mat as
Mat matData(opcvImg, true);
OR
Mat matData = cvarrToMat(opcvImg);
matData in the watch window shows Unavailable syschronous data.Let me put in some more information, actually the code runs in a separate thread as follow
@void processingbyWatershed::run()
{
IplImage *opcvImg = cvCreateImage(cvSize(col_size, row_size), IPL_DEPTH_8U,1);while(1) { if(!ImageQueue::isEmpty()) { opcvImg = ImageQueue::getQueue(); Mat original(opcvImg, true); //Mat original = cvarrToMat(opcvImg); } }
}@
What could be the problem?
Thanks -
This does not look like Qt-related problem. You would probably be better off asking this on OpenCV-related forum or mailing list.

No, my query is can I have a hint of what are the possible causes of making matData to be Unavailable syschronous data.

What version of QtCreator / GCC / GDB are you using?
-
I am using QT Creator 2.4.1

Try upgrading to 2.6+ and a recent GDB (as for example distributed with "MinGW-builds":http://sourceforge.net/projects/mingwbuilds/). There are known problems with older versions of GDB which result in the error you've mentioned.
