asked 2013-05-06 00:23:14 -0500

Hi,there. I want to find some infomation about this class "class CV_EXPORTS LDetector", but I can't find it in the opencv document. How could this happen? My opencv version is 2.4.1.

It just isn't documented, there is already assigned a ticket at, so there is no need to assign another one, however you can leave a note there that you actually use (or want to use) the descriptor.

If you want to speed up things you can read the original paper (Vincent Lepetit, Pascal Fua,"Towards Recognizing Feature points Using Classification Trees," Technical Report IC/2004/74, EPFL, 2004.), figure out how it works (/legacy/src/planardetect.cpp) and add the missing documentation to OpenCV. Please see how you can contribute.

What is CV_EXPORTS? I see this macros in so many places. But could not really understand what it is. There is no information about it also. I also want to know what NCV_STATUS and NCV_EXPORTS is? what is the difference between CV and NCV? can anyone enlighten me?

@mainul, please start a new question on this, since having several topics on one side is a total drag, thank you!
