Does anyone know what the Facebook "3D Photos" feature is doing and how/if it's different to this? Because that is generally terrible (much worse than the 'failure mode' examples here) and the depth map generated seems largely arbitrary.
- andybak 6y agoIt's worth making a distinction between "3D Photos where the user supplies depth data from the dual cameras/LIDAR etc" vs "3D Photos where Facebook's magic algorithms try to infer depth". It's the latter that I presume you're criticising here. (Might be obvious to you but I thought it worth spelling out)
- ben_w 6y agoI think this paper is also about the latter, it’s just a much better version of the latter - the abstract says RGB image not RGBZ, and one of the examples is a painting.
- taneq 6y agoTrue, and the latter is indeed what I was referring to. This looks like it does the same thing as Facebook's (train a neural net to infer depth from image contents) but it actually works fairly well. Generating new views from an rgb+depth image is relatively straightforward and I'd expect any reasonable implementation to work pretty well.
- moetsi 6y agothe latter was 6d.ai's whole thing. I say "was" because they were bought by Niantic
