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

Researchers introduced PRIMA, a 3D animal mesh recovery framework that combines BioCLIP-based biological priors with test-time adaptation.

PRIMA uses 2D reprojection and keypoints at inference time to better recover meshes for unusual poses and underrepresented species.

The team also built Quadruped3D, a large pseudo-3D dataset, to support training and evaluation.

PRIMA reports state-of-the-art results across multiple animal reconstruction benchmarks, improving reliability and scalability.
