NeRFs: Neural Radiance Fields - Paper Explained

what is going on guys in this video i want to um explain the paper uh behind the nerves or neural radiance fields and i want to introduce the concept of nerves uh basically you know i want to explain how they work um what they do um and so on and if this video is something that is interesting to people um and would be interesting to make a sort of from scratch implementation then let me know and i can get working on that depending on how on how popular that would be so i want to explain in a way that's easy that doesn't take too long hopefully i don't know how long this video is going to be but hopefully i'm aiming for 10 minutes we'll see if i get there it's probably going to be longer than 10 minutes but yeah all right so uh let's just start with um you know what is the goal of nerfs and uh the idea is uh that we we um we basically have some like we take a bunch of different images of this drum from different viewing angles as you can see here and the idea is that we can then train nerf or run nerve optimize nerve and then we can synthesize a a view of this of this drum kit um or this scene in general it's not a particular object it's a scene so basically make a 3d reconstruction from a multi-view image input so from 2d images viewed from different angles we can reconstruct a 3d scene and we can render new views so here's an example they have from the paper where basically have like a dozen of photos that are very like jumpy in the representation but then when we uh use nerves we get this very smooth uh sort of transition
