Problem with cv::Mat and IplImage

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Trying to stick to the rules of OpenCV 2.1 and using cv::Mat instead of 
IplImage.
2. Feeding cvLabel() with a cv::Mat doesn't work, converting the mat to and 
IplImage also doesn't work because of the const parameter needed.

What is the expected output? What do you see instead?
I think it should either work with cv::Mat or IplImage without a need for the 
cast!?

What version of the product are you using? On what operating system?
OpenCV 2.1 on OSX, latest cvBlob release.

Please provide any additional information below.

Sorry, my fault. I was too stupid to dereference the pointer... ;)

Hi Christoph!

Actually, I've never have used `cv::Mat` :-S 

Can you confirm it works with cvBlob functions?

Thank you very much!

Yes, it does. You just need to assign an IplImage the cv::Mat (like really just 
assign it), and use it. It's even on the cheatsheet 
(http://opencv.willowgarage.com/documentation/cpp/c++_cheatsheet.html).

Cheers,
Christoph
