Lift4D: Harmonizing Single-View 3D Estimation for 4D Reconstruction In-the-Wild
- darepublic 4mo agoI'm sorry but this just reminds me of this tng episode that inspired me as a teen https://www.youtube.com/watch?v=4Faiu360W7Q https://www.youtube.com/watch?v=4Faiu360W7Q
- poly2it 4mo agoThis is insanely promising. What a time to be alive!
- Joel_Mckay 4mo agoTwo Minute papers fan? fun YT channel =3
- tamimio 4mo agoCool, so now when the swarm drones come after you, they can reconstruct the video on the fly from that single CCTV shot taken by flock, and pinpoint your location from the aggregated data by plantir!
- bensmoif 4mo agoReally interesting, and a link to your GitHub with a "code coming soon". Please get us the tool already!
- christianh 4mo agoLooks cool. How’s it different from https://github.com/gaomingqi/sam-body4d https://github.com/gaomingqi/sam-body4d ? My guess: Is sam-body4d focused on temporally consistent body reconstruction into an MHR model, and Lift4D creates the full scene and a model of the tracked object (that doesn’t need to be a human). I may be way off, but a comparison would help me!
- fraywing 4mo agowondering how accurate the extrapolated distances are? Like the Rhino and the tree -- I wonder if the approximation could be useful in something like forensics from a security video?
- avaer 4mo ago> I wonder if the approximation could be useful in something like forensics from a security video? No. It's just some plausible thing the AI made up. It's literally like asking an LLM to generate evidence of a crime based on the prompt you presented. There are plenty of cool use cases, just not forensics.
- gpm 4mo agoUsed properly I could imagine legitimate forensics uses to 3d reconstruction and splatting. For example as a "map" to find what underlying data (e.g. video frames) captured the thing.

- avaer 4mo agoI hope no court ever accepts AI generated evidence.
- jmpman 4mo agoCan someone use this on Elon's "my heart goes out to you" video, and compare it to... similar gestures. Would be interested to see exactly how close it is.
- waste_monk 4mo agoJust reading the first word of the title made me think about what a lift (elevator) simulator a la Elevator Saga[1] but in 4 spatial dimensions would look like. [1] https://play.elevatorsaga.com https://play.elevatorsaga.com
