Running grabCut causes JRE fatal error. #143

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago
G'Day All,

I have the following code snippet (attached) that demonstrates the issue with 
using grabCut (mypc = Win64).

This is the file I used as a refference on how to use grabcut: 
https://code.ros.org/svn/opencv/trunk/opencv/samples/cpp/grabcut.cpp

Any help would be very appreciated.

Opps, forgot this, the error message text is as follows:
OpenCV Error: Bad argument (Unknown array type) in unknown function, file 
C:\slave\WinInstallerMegaPack\src\opencv\modules\core\src\matrix.cpp, line 646

Opps, just saw I left a bit of my internal code in there. 
This is the same file again (showing the same problem), but ready to compile 
with just opencv.

Well, let's see.
1. `new CvMat()` does not initialize the memory to anything valid for OpenCV, 
call `new CvMat(null)` instead
2. `grabCut()` does not support images of type `IPL_DEPTH_1U`. Almost nothing 
in OpenCV actually supports that type, just use `IPL_DEPTH_8U`.
3. Do not call `IplImage.release()` on images not created by a 
`IplImage.create*()` factory method.

And please post your questions on the mailing list next time, thank you!
