Text2Control3D: Controllable 3D Avatar Generation in Neural Radiance Fields using Geometry-Guided Text-to-Image Diffusion Model

no code implementations7 Sep 2023 Sungwon Hwang, Junha Hyung, Jaegul Choo

Our main strategy is to construct the 3D avatar in Neural Radiance Fields (NeRF) optimized with a set of controlled viewpoint-aware images that we generate from ControlNet, whose condition input is the depth map extracted from the input video.

FaceCLIPNeRF: Text-driven 3D Face Manipulation using Deformable Neural Radiance Fields

no code implementations ICCV 2023 Sungwon Hwang, Junha Hyung, Daejin Kim, Min-Jung Kim, Jaegul Choo

To do so, we first train a scene manipulator, a latent code-conditional deformable NeRF, over a dynamic scene to control a face deformation using the latent code.

Local 3D Editing via 3D Distillation of CLIP Knowledge

no code implementations CVPR 2023 Junha Hyung, Sungwon Hwang, Daejin Kim, Hyunji Lee, Jaegul Choo

Specifically, we present three add-on modules of LENeRF, the Latent Residual Mapper, the Attention Field Network, and the Deformation Network, which are jointly used for local manipulations of 3D features by estimating a 3D attention field.

Low-level Pose Control of Tilting Multirotor for Wall Perching Tasks Using Reinforcement Learning

no code implementations11 Aug 2021 Hyungyu Lee, Myeongwoo Jeong, Chanyoung Kim, Hyungtae Lim, Changgue Park, Sungwon Hwang, Hyun Myung

In this paper, a novel reinforcement learning-based method is proposed to control a tilting multirotor on real-world applications, which is the first attempt to apply reinforcement learning to a tilting multirotor.

Equivariance-bridged SO(2)-Invariant Representation Learning using Graph Convolutional Network

2 code implementations18 Jun 2021 Sungwon Hwang, Hyungtae Lim, Hyun Myung

Training a Convolutional Neural Network (CNN) to be robust against rotation has mostly been done with data augmentation.

ERASOR: Egocentric Ratio of Pseudo Occupancy-based Dynamic Object Removal for Static 3D Point Cloud Map Building

3 code implementations7 Mar 2021 Hyungtae Lim, Sungwon Hwang, Hyun Myung

However, when it comes to constructing a 3D point cloud map with sequential accumulations of the scan data, the dynamic objects often leave unwanted traces in the map.
