Core Concepts
The author introduces Fine Structured-Aware Sampling (FSS) as a new training scheme to enhance pixel-aligned implicit models for single-view human reconstruction, focusing on capturing thin body features effectively.
Abstract
Fine Structure-Aware Sampling (FSS) is proposed to address the limitations of existing sampling training schemes for pixel-aligned implicit models. FSS introduces key features like twinned sample points, proximity-adaptive displacement, anchor sample points, counter sample points, and Smplx-guided sampling to improve the reconstruction of thin body features. Additionally, FSS incorporates the use of normals of sample points and mesh thickness loss signals to further enhance model training and accuracy. The results show that FSS outperforms state-of-the-art methods both qualitatively and quantitatively in single-view clothed human reconstruction tasks.
The content discusses the importance of different components within the FSS scheme such as twinned sample points, proximity-adaptive displacement, anchor sample points, counter sample points, and Smplx-guided sampling. It also explores the utilization of normals of sample points and mesh thickness loss signals to improve model training and accuracy. The study concludes with a comparison against existing state-of-the-art methods in single-view clothed human reconstruction tasks.
