Please write in  your initial proposal based on the orientations at . Then contact the mentors of that project (in copy), they will give you feedback to improve your proposal until the deadline, including the "Final" PDF proposal. There "Final" is not immutable, you can replace it until the deadline, until the submission.
Regarding Project#1 Eduardo will not mentor it so you can safely remove him from the email interactions. I will mentor it so include me in the interactions.
The main goal of Project#1 is to build several exercises in JdeRobot Academy so new students may learn computer vision. From the basic image processing (as color filtering, edge detection, optical flow...) to more advanced ones. Take a look at several existing Computer Vision introductory courses and think about what practical exercises would be nice for them.
Those Academy exercises should work both with regular off-the-shelf real cameras and also with videos. Both of them using ROS drivers, so the Academy ROS nodes for those exercises may subscribe to image ROS topics. Working with real cameras, as webcams, is the target scenario as they are ubiquitous and they are more illustrative than videos. Offline videos (or ROSbags) are also desirable as they allow the evaluation of many student's code with exactly the same visual input.
