InterHandGen: Two-Hand Interaction Generation via Cascaded Reverse Diffusion

no code implementations26 Mar 2024 Jihyun Lee, Shunsuke Saito, Giljoo Nam, Minhyuk Sung, Tae-Kyun Kim

Sampling from our model yields plausible and diverse two-hand shapes in close interaction with or without an object.

A Local Appearance Model for Volumetric Capture of Diverse Hairstyle

no code implementations14 Dec 2023 Ziyan Wang, Giljoo Nam, Aljaz Bozic, Chen Cao, Jason Saragih, Michael Zollhoefer, Jessica Hodgins

In this paper, we present a novel method for creating high-fidelity avatars with diverse hairstyles.

Relightable Gaussian Codec Avatars

no code implementations6 Dec 2023 Shunsuke Saito, Gabriel Schwartz, Tomas Simon, Junxuan Li, Giljoo Nam

The fidelity of relighting is bounded by both geometry and appearance representations.

Differentiable Display Photometric Stereo

no code implementations23 Jun 2023 Seokjun Choi, Seungwoo Yoon, Giljoo Nam, Seungyong Lee, Seung-Hwan Baek

In this paper, we present differentiable display photometric stereo (DDPS), addressing an often overlooked challenge in display photometric stereo: the design of display patterns.

Event Fusion Photometric Stereo Network

no code implementations1 Mar 2023 Wonjeong Ryoo, Giljoo Nam, Jae-Sang Hyun, Sangpil Kim

We present a novel method to estimate the surface normal of an object in an ambient light environment using RGB and event cameras.

Neural Strands: Learning Hair Geometry and Appearance from Multi-View Images

no code implementations28 Jul 2022 Radu Alexandru Rosu, Shunsuke Saito, Ziyan Wang, Chenglei Wu, Sven Behnke, Giljoo Nam

Furthermore, we introduce a novel neural rendering framework based on rasterization of the learned hair strands.

ORA3D: Overlap Region Aware Multi-view 3D Object Detection

no code implementations2 Jul 2022 Wonseok Roh, Gyusam Chang, Seokha Moon, Giljoo Nam, Chanyoung Kim, Younghyun Kim, Jinkyu Kim, Sangpil Kim

Current multi-view 3D object detection methods often fail to detect objects in the overlap region properly, and the networks' understanding of the scene is often limited to that of a monocular detection network.

HVH: Learning a Hybrid Neural Volumetric Representation for Dynamic Hair Performance Capture

no code implementations CVPR 2022 Ziyan Wang, Giljoo Nam, Tuur Stuyck, Stephen Lombardi, Michael Zollhoefer, Jessica Hodgins, Christoph Lassner

Capturing and rendering life-like hair is particularly challenging due to its fine geometric structure, the complex physical interaction and its non-trivial visual appearance. Yet, hair is a critical component for believable avatars.

Strand-Accurate Multi-View Hair Capture

no code implementations CVPR 2019 Giljoo Nam, Chenglei Wu, Min H. Kim, Yaser Sheikh

Thus, in the second stage, we feature a novel strand reconstruction method with the mean-shift to convert the noisy point data to a set of strands.
