Here's BANMo, a NeRF-inspired approach shared at the CVPR 2022 event I attended a few weeks ago. BANMo takes pictures to create deformable 3D models. If you are in VFX, game development, or creating 3D scenes, this new AI model is for you. I wouldn’t be surprised to see this model or similar approaches in your creation pipeline very shortly, allowing you to spend much less time, money, and effort on making 3D models.

development or 0:02 creating 3D scenes this new AI model is 0:06 for you I wouldn't be surprised to see 0:08 this model or similar approaches in your 0:10 creation pipeline very shortly allowing 0:12 you to spend much less time money and 0:14 effort on making 3D models just look at 0:18 that of course it's not perfect but that 0:20 was done instantly with a casual video 0:23 taken from a phone it didn't need an 0:25 expensive midi camera setup or complex 0:28 depth sensors one of the Beauties behind 0:31 AI making complex and costly 0:33 Technologies available for startups are 0:35 single individuals to create projects 0:37 with professional quality results just 0:40 film an object and transform it into a 0:42 model you can import right away you can 0:45 then fine tune the details if you are 0:46 not satisfied but the whole model will 0:49 be there within a few seconds what 0:51 you've been seeing are the results from 0:52 an AI model called banmu recently shared 0:55 at the cvpr event I attended I'll be 0:58 honest they got my attention because 1:00 because of the cats still it wasn't 1:02 completely clickbait the paper and 1:05 approach are actually pretty awesome it 1:07 isn't like the other Nerf approach to 1:09 reconstructing objects in 3D models 1:11 banned mode tackles a task recall 1:13 articulated 3D shape reconstruction 1:16 which means it works with videos and 1:18 pictures to model deformable objects and 1:22 what's more deformable than a cat and 1:24 what's even cooler than seeing the 1:26 results is understanding how it works 1:29 the model starts with a few casually 1:31 taken videos of the object you want to 1:34 capture showing how it moves and deforms 1:36 itself that's where you want to send a 1:38 video of your cat slurping into a vase 1:41 bamboo takes those videos to create then 1:44 what they refer to as a canonical space 1:47 this initial result will give you 1:49 information about the object's shape 1:51 appearance and articulations it's the 1:53 model's understanding of your object's 1:55 shape how it moves through space and 1:57 where it belongs between a brick and a 1:59 blood described by those big balls and 2:01 various colors it then takes this 3D 2:04 representation and applies any pose you 2:06 want simulating the cat's behavior and 2:08 articulations as close to reality as 2:11 possible seems like magic doesn't it 2:13 that's because we are not done here we 2:16 quickly went from a video to the model 2:18 but this is where it becomes interesting 2:20 so what do they use to go from images of 2:23 a video to such a representation in this 2:25 canonical space you guessed it a 2:28 nerf-like model if you are not familiar 2:30 with this approach I strongly invite you 2:32 to watch one of the many videos I made 2:34 covering them and come back for the rest 2:36 insert the Nerf inspired method will 2:39 have to predict three essential 2:40 properties used for each 2:42 three-dimensional pixel or voxels of the 2:46 object as you see here color density and 2:49 a canonical embedding using a neural 2:51 network trained for that to achieve a 3D 2:54 model with realistic articulations and 2:56 movement banmu uses the camera's spatial 2:59 location in multiple frames to 3:01 understand the array from which it is 3:03 filming allowing it to reconstruct and 3:05 improve the 3D model iteratively through 3:07 all frames of the videos similar to what 3:10 we will do to understand an object move 3:12 it around and look at it in all 3:14 directions this part is done 3:16 automatically by observing the videos 3:18 thanks to the canonical embedding we 3:20 just mentioned this embedding will 3:22 contain all necessary features of each 3:24 part of the object to allow you to query 3:27 with a new desired position for the 3:29 object and forcing a coherent 3:31 reconstruction given observations it 3:33 will basically map The Wanted position 3:35 from the picture up to the 3D model with 3:38 the correct viewpoints and lighting 3:40 conditions and provide Q is for the 3:42 needed shape and articulations one last 3:45 thing to mention is our colors those 3:47 colors represent the cat's body 3:49 attributes shared in the different 3:51 videos and images we used this is the 3:54 feature we will learn and look at to 3:57 take valuable information from all 3:59 videos and merge them in the same 3D 4:01 model to improve our results and voila 4:05 you end up with this beautiful 3D 4:08 deformable calorie cut you can use in 4:10 your applications of course this was 4:13 just an overview of banmu and I invite 4:15 you to read the paper for a deeper 4:17 understanding of the model you should 4:19 definitely subscribe to the channel if 4:21 this kind of AI news interests you as 4:23 I'm sharing similar exciting approaches 4:26 every week thank you for watching until 4:28 the end and I will see you next week 4:30 with another amazing paper 4:32 foreign 4:36 [Music]
