SPAMs: Structured Implicit Parametric Models

no code implementations CVPR 2022 Pablo Palafox, Nikolaos Sarafianos, Tony Tung, Angela Dai

We observe that deformable object motion is often semantically structured, and thus propose to learn Structured-implicit PArametric Models (SPAMs) as a deformable object representation that structurally decomposes non-rigid object motion into part-based disentangled representations of shape and pose, with each being represented by deep implicit functions.
