REGIR: Refined Geometry for Single-Image Implicit Clothed Human Reconstruction (ICASSP2024)

Contribution:

• A novel query point encoding utilizing pixel-aligned feature, voxel-aligned feature, and SDF.
• coarse-to-fine implicit model based on multi-level voxel-aligned feature for 3D human reconstruction.

This project is built upon ICON, and the core idea of the work is inspired by PIFuHD.
