PRIMA: Boosting Animal Mesh Recovery with Biological Priors and Test-Time Adaptation

ArXi:2606.02366v1 Announce Type: new We present PRIMA (*PRI*ors for *M*esh *A*daptation), a framework for robust 3D quadruped mesh recovery under severe species and pose imbalance. Existing animal reconstruction methods often regress toward mean shapes and poses due to limited 3D supervision and long-tailed species distributions, resulting in poor generalization to underrepresented animals and rare articulations. PRIMA addresses this challenge through three key contributions.
