For hydro, we could not compile simple_compressed_example_nodelet.cpp and lk_flow lk_flow. Please see following PR. https://github.com/ros-perception/opencv_apps/pull/23/files

ok, i have fixed the PR, please look at code, lk_flow is able to compile just adding 1 header file, and simple_compressed_example_nodelet is not a easy one, but you can fix that.
