HumanSplatHMR: Closing the Loop Between Human Mesh Recovery and Gaussian Splatting Avatar

Katherine A. Skinner, Pou-Chun Kung, Ram Vasudevan, Seth Isaacson, Yeheng Zong, Yike Pan, Yizhou Chen

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Experiments show consistent improvements over pose recovery baselines that omit image-level refinement and avatar baselines that decouple pose estimation from avatar reconstruction.

C2weakest assumption

That backpropagating photometric, segmentation, and depth losses through the differentiable renderer will reliably refine global 3D poses without introducing instability or local minima that degrade the avatar quality.

C3one line summary

HumanSplatHMR closes the loop between human mesh recovery and Gaussian Splatting by using photometric, segmentation, and depth losses to refine poses during avatar optimization.
