Different from existing single-view methods which can only recover a 2. 5D scene representation (i. e., a normal / depth map for the visible surface), our method learns a neural reflectance field to represent the 3D geometry and BRDFs of a scene.

JIFF: Jointly-aligned Implicit Face Function for High Quality Single View Clothed Human Reconstruction

no code implementations • CVPR 2022 • Yukang Cao, GuanYing Chen, Kai Han, Wenqi Yang, Kwan-Yee K. Wong

In this paper, we focus on improving the quality of face in the reconstruction and propose a novel Jointly-aligned Implicit Face Function (JIFF) that combines the merits of the implicit function based approach and model based approach.
