If you installed ros-indigo-opencv3, please try following steps.

mkdir -p ~/ws_opencv_apps/src
cd ~/ws_opencv_apps/src
cd ~/ws_opencv_apps
catkin init
cd ~/ws_opencv_apps/src
wstool init
wstool set --git opencv_apps https://github.com/ros-perception/opencv_apps.git -y
rosinstall_generator image_pipeline --upstream >> .rosinstall.opencv3; fi # need to recompile image_proc
rosinstall_generator compressed_image_transport --upstream >> .rosinstall.opencv3; fi # need to recompile compressed_image_transport
rosinstall_generator vision_opencv --upstream >> .rosinstall.opencv3; fi # need to recompile visoin_opencv
wstool merge .rosinstall.opencv3; fi # need to recompile visoin_opencv

@iory why you assume @parhartanvir is using opencv3
@parhartanvir running with opencv3 on indigo is super experimental settings, we do not recommend to use that, even if works for opencv_apps, it will have side-effects to other repository
@parhartanvir please provide OS version, ROS version when you run your application,

roslaunch --screen opencv_apps lk_flow.launch image:=one_image_raw

will show more information and also lk_flow-1*.log is empty, please check other files in /home/frcvision/.ros/log/c914a1be-ffac-11e6-88c1-d8cb8ac73819/

I have seen a similar error, and I suspected it was the effect of opencv3.
