I want to study the feature matching algorithms, I know there are many methods in the FLANN library for nearest neighbor searching, does the opencv 2.4.3 include the latest FLANN library version like flann-1.8.3-src or above 1.7 ?

According to the header file the version in OpenCV is based on 1.6.10:

#define FLANN_VERSION_ "1.6.10"

That being said, if you want to dig into nn-search methods I recommend to use the original FLANN version - not the version shipped with OpenCV, because the latter is the dark side of OpenCV. E.g. there are many wrappers around FLANN's types and confusingly named objects and namespaces. I found it a pain to use.

However, if you just want to use the FlannBasedMatcher the OpenCV version is fine.
