Can we use OpenMP with latest version of openCV

I want to parallelize my image processing codes using openMP. I have a doubt if OpenMP is supported by the latest versions of OpenCV like 2.4.4 or 2.4.5 versions. I know abt TBB but looks too complicated.

You might consider looking into cv::parallel_for_(). It provides a layer of abstraction for several parallelism mechanisms. If you have compiled OpenCV with OpenMP support, cv::parallel_for_() will use OpenMP when it can. Many OpenCV functions use cv::parallel_for_ intenally, but you might have to dig into the source to see whether parallel execution is actually happening.
