AvaImg Teaser

AvaImg produces high-fidelity SMPL-X+D registrations with UV texture and displacement maps, enabling re-animation, texture editing, shape editing, and more.

Registration Gallery

Gallery of AvaImg registrations across three datasets. Each triplet shows (left to right): the textured input scan, the neutral SMPL-X body fit, and the high-resolution surface registration with applied texture.

Comparison with Dataset Ground Truth

We overlay the fitted body mesh on the clothed scan surface. Red vertices indicate body parts penetrating through clothing, a physically impossible artifact. Dataset ground-truth registrations exhibit pervasive penetration, while AvaImg keeps the body enclosed within clothing.

Comparison with Baselines

Side-by-side qualitative comparison of AvaImg against state-of-the-art SMPL fitting and registration methods.

Applications

Because all registrations share SMPL-X topology and a coherent UV layout, AvaImg directly supports (a) re-animation, (b) texture editing & transfer, (c) shape editing, (d) dense shape correspondence, and (e) material editing.

Applications: re-animation, texture editing and transfer, shape editing, shape correspondence, material editing
