I tried to detect a marker using aruco_ros using two following launch files and faced the same problem. roslaunch usb_cam usb_cam-test.launch roslaunch aruco_ros aruco-test.launch

visualizing "/aruco_single/debug/compressed" topic using "rosrun rqt_gui rqt_gui" or through rviz gives this: image description

I received 2 warnings: [ WARN] : Corner refinement options have been removed in ArUco 3.0.0, corner_refinement ROS parameter is deprecated [ WARN] : normalizeImageIllumination is unimplemented! I think the source of the flickering problem is the latter warning! but I didn't find a solution for it yet!
