Andrea Tagliasacchi: Do you like implicit functions to model 3D geometry?
We show that "Neural Articulated Shape Approximation" improves the approximation power by over 50% ABSOLUTE!!
Fast-forward of our #ECCV paper, full talk, additional material, and code comings soon.

Andrea Tagliasacchi: Double-blind is great, so why cannot #arXiv add an "anonymous till published" mode?
The authors could then be revealed only once the paper is full peer-reviewed (or after a cutoff date), and you could still cite them, thanks via https://arxiv.org/abs/1912.03207

Nima Ghorbani: It is a wonderful, and humbling feeling to walk back home waiting to read two papers in your backpack during the holidays, which build on your previous work and go beyound what you could have achieved before! VIBE: https://arxiv.org/abs/1912.05656 and NASA: https://arxiv.org/abs/1912.03207

Andrea Tagliasacchi: @gabrielpeyre @GerardPonsMoll1 And this has applications in vision/geometry (registration of deformable bodies) where this convolution can be replaced by an expectation → https://arxiv.org/pdf/1912.03207.pdf https://t.co/CcUZFmweFK

Daisuke Okanohara: NASA is the first neural implicit rig and can represent the shape of articulated objects. Each part is represented by an implicit function with a position and parameters being transformed by the pose. The whole is represented by their union (max op.). https://arxiv.org/abs/1912.03207
