SideGAN: 3D-Aware Generative Model for Improved Side-View Image Synthesis

no code implementations19 Sep 2023 Kyungmin Jo, Wonjoon Jin, Jaegul Choo, Hyunjoon Lee, Sunghyun Cho

In this paper, we propose SideGAN, a novel 3D GAN training method to generate photo-realistic images irrespective of the camera pose, especially for faces of side-view angles.

ContraNeRF: 3D-Aware Generative Model via Contrastive Learning with Unsupervised Implicit Pose Embedding

no code implementations27 Apr 2023 Mijeong Kim, Hyunjoon Lee, Bohyung Han

Although 3D-aware GANs based on neural radiance fields have achieved competitive performance, their applicability is still limited to objects or scenes with the ground-truths or prediction models for clearly defined canonical camera poses.

CTRL-C: Camera calibration TRansformer with Line-Classification

1 code implementation ICCV 2021 Jinwoo Lee, Hyunsung Go, Hyunjoon Lee, Sunghyun Cho, Minhyuk Sung, Junho Kim

In this work, we propose Camera calibration TRansformer with Line-Classification (CTRL-C), an end-to-end neural network-based approach to single image camera calibration, which directly estimates the camera parameters from an image and a set of line segments.

Camera Calibration Classification

Neural Geometric Parser for Single Image Camera Calibration

1 code implementation ECCV 2020 Jinwoo Lee, Minhyuk Sung, Hyunjoon Lee, Junho Kim

With the supervision of datasets consisting of the horizontal line and focal length of the images, our networks can be trained to estimate the same camera parameters.
