Is it possible to use an older version of OpenCV with ROS Groovy (current version is 2.4.4)? If so, how could I change to a different version?

Out of curiosity, why do you want to do this?

My team was using the cvblobslib to do some object localization. When we used 2.4.4, everything builds, but the blob detection (cvblobslib) doesn't work. Compiled on our old machine with Fuerte and OpenCV 2.4.2, it does work. We ended up re-writing our program to work with a different blob library.

Huh. If you haven't, it might be good to file a bug against cvblobslib, just to let them know that OpenCV changed out from under them.

If you want a different version of OpenCV you should create a workspace with all packages which depend on it and the older version of OpenCV and compile from source.
