Hi, I am a student of Bachelors of sciences in computer science. My final year project is on scene semantic analysis and map reconstruction using multiple autonomous robots. I am using Ubuntu 12.04 Ros-fuerte and turtlebots. So I was wondering if someone can help me with object recognition packages and saliency detection packages tutorials. i know the names of packages but dnt know how to use them. What i have already done is working turtlebot simulation i have used teleop to navigation so far and created a 3D map with RGBDSLAM. Thanx =)
