Getting started with open source development

I want to start contributing in open source development. But as I am new I have no idea ( and also no confidence) how to find projects on Github in which I can contribute. Is there any suggestion how to get started? I am particularly interested in computer vision. Can somebody suggest me how to find relevant papers/projects?

Does this help?

Not really. When I will try to touch some well known project like Tensorflow there is always a thought in my mind that I am a new learner, how there be an error which I can fix as the projects are already seen by a lot of people.
Suppose, I finished the deep learning specialization computer vision course. Now I want to find some computer vision projects which I can understand and also do something on that. How can I find a project related to my present knowledge from the huge set. I want some guidance/suggestion how should start my journey…
