Why there are two versions of openCV 3.x and 2.4.xx ? I 'm still confused , which one should I select , the two versions seems to be active , is there any plan to stop one of them , what is the rule used to select which version is suitable for my application.
It has some historical reasons why both systems exist.
So basically
Good luck!
Thanks @StevenPuttemans , very good answer , sorry I want ask you another question, I want build module to be easy ported from OS to another , I will start to build the module as dll for windows , then I will port it to linux , ios, android , so what is OpenCV version will be used ?
The OS is no parameter in selecting the right version in my opinion, since OpenCV can be build on most systems without problems.
Thanks @StevenPuttemans , as I know that ios uses objective C , and as you said in the answer OpenCV 3.x uses c++ , so is it possible from objective c call c++ module ?
With that I have no exp ... I did a single project in objective C once and left the platform after that ... it just amazes me that people seem the be using it. It is about the most user unfriendly interface you can imagine with all those extra apple directives :D
I found the following link OpenCV 3.0 introduction the link is complemtary to @StevenPuttemans answer.
Hi @StevenPuttemans , your answer is perfect and if I have more voting I will give it for your answer, but the link in my answers describes difference more explanation , the link and your answer are complamntary to each other , I will remove my comment on the link answer .
Keep in mind that since I wrote this topic, we basically took a step further. 2.x is now in somehow a freezed state, and only gets critical fixes. 3.x is the main branch for now, having latest functionality. However there is a 4.x development branch, which took the switch to C++11 and has a lot of new and exciting things. In the next couple of months this will be the new official main branch my guess.
