18 Humans in Videos What is something you have learned that we may not know? People don’t know how difficult sign language is and about the computer vision problems involved with it. It’s not a simple gesture recognition problem. It’s a language problem. It’s like any language, with all the grammar and vocabulary rules, but italsohas thevisual aspects, sowehave to deal with video representation learning and language learning. It’s considered a low-resource language for machine translation because you don’t have more than 1 million sentences. Before getting into this field, I didn’t realize it required know-how from so many adjacent fields. That made the problem super interesting. I would encourage people to work on it. How long will the sign language problem take to be solved? It might be a 50% chance in 10 years. It’s What other field would you have chosen if you could not do this? I was also thinking of becoming a math teacher, but I’m in a field related to math, and in a way, I’m a teacher, so that’s not too far. At one point, I wanted to become a film director, and that does seem far now! Considering everything you work on, how much came along organically, and how much was chosen by you? Sign language is the thing that happened as part of my postdoc because the funding was coming from that. I hadn’t determined it, but I liked it after getting into it. Human motion is from me. Video retrieval, video representations, and everything about video in general is what I’m passionate about, mainly because it’s very difficult. There are so many open questions.
