Assuming the user has opencv and ros installed on their system.

Task 1
To compile the file, go to AUV_TaskRound/Task1
Edit line 20 of a.cpp to point to video file
Now Run the following on a terminal from folder Task1

1. $make a
2. $./a

Task 2
To compile the file, go to AUV_TaskRound/Task2
Edit line 77 of track2.cpp to point to video file (best output on "frontcam.avi")
Now run the following on a terminal from folder Task2

1. $make track2
2. $./track2
   Press any key to move from one frame to next

Task 3
ROS package Structure:
catkin_ws
\ -build //build files
\ -devel
\ -src //This folder contains the actual source code
\ \ -auv_task //Code for the tasks
\ \ -include
\ \ -src //Source code
\ \ \ -kalman.cpp //Kalman Filter Code
\ \ \ -listener.cpp //Node to publish measurements
\ \ \ -talker.cpp //Node to publish video feed
\ \ \ -trackerdisp.cpp //Node to display video feed with predictions
\ \ -CMakeLists.txt
\ \ -package.xml
\ -beginner_tutorials //not relevant to this submission

Edit line 33 of talker.cpp to point to video file (best output on "frontcam.avi")
To compile the file, go to AUV_TaskRound/catkin_ws.
This folder is a catkin workspace that contains package auv_task,which is to be run.
Copy-paste the AUV_TaskRound/catkin_ws/auv_task folder into a workspace on your machine.
Then run the following on a terminal from your workspace-
$catkin_make
$roscore

In another terminal run
$source ./devel/setup.bash
$rosrun auv_task talker_image

In another terminal run
$source ./devel/setup.bash
$rosrun auv_task listener_image

In another terminal run
$source ./devel/setup.bash
$rosrun auv_task kalman

In another terminal run
$source ./devel/setup.bash
$rosrun auv_task trackerdisp

All 5 terminals need to be running simultaneously for the program to function
