image tracking node python
I am using Ubuntu 16.04, ROS Kinetic and Python 2.7.12. I want to run a complicated code in python, which can read an avi document frame by frame, apply some filters, and export three csv documents and one new avi document. I am new in ROS and I am not sure how exactly is going to be. Can I make it only by creating a publisher node in Python? Do I have to publish in a different topic in the same node, for every different type of my data? (for example avi anf csv documents) Any possible solution or a guideline would be appreciated.
If you are just reading and writing to avi and csv, why do you need ROS ?
This will be a part of a bigger project, which will combine different applications controlled under a common platform (ROS)
