I am a Ph.D. student at University of Maryland, College Park (UMD).

At UMD I've worked on computer vision and autonomous navigation systems. I did my MS at KAIST, where I was advised by Changick Kim. I did my bachelors at the KAIST.

Research

I'm interested in computer vision, machine learning, and robotics.

DnD: Dense Depth Estimation in Crowded Dynamic Indoor Scenes
Dongki Jung*, Jaehoon Choi*, Yonghan Lee, Deokhwa Kim, Changick Kim, Dinesh Manocha, Donghwan Lee
ICCV, 2021
arXiv

We present a novel approach for estimating depth from a monocular camera as it moves through complex and crowded indoor environments.

Just a Few Points are All You Need for Multi-view Stereo: A Novel Semi-supervised Learning Method for Multi-view Stereo
Taekyung Kim, Jaehoon Choi, Seokeon Choi, Dongki Jung, Changick Kim
ICCV, 2021
arXiv

We first introduce a novel semi-supervised multi-view stereo framework.

SelfDeco: Self-Supervised Monocular Depth Completion in Challenging Indoor Environments
Jaehoon Choi, Dongki Jung, Yonghan Lee, Deokhwa Kim, Dinesh Manocha, Donghwan Lee
ICRA, 2021
arXiv

We present a novel algorithm for self-supervised monocular depth completion in challenging indoor environments.

SAFENet: Self-Supervised Monocular Depth Estimation with Semantic-Aware Feature Extraction
Jaehoon Choi*, Dongki Jung*, Donghwan Lee, Changick Kim
NeurIPS Workshop on Machine Learning for Autonomous Driving, 2020
arXiv

We propose SAFENet that is designed to leverage semantic information to overcome the limitations of the photometric loss.

Arbitrary Style Transfer Using Graph Instance Normalization
Dongki Jung, Seunghan Yang, Jaehoon Choi, Changick Kim
ICIP, 2020
arXiv

We present a novel learnable normalization technique for style transfer using graph convolutional networks

Self-Ensembling with GAN-based Data Augmentation for Domain Adaptation in Semantic Segmentation
Jaehoon Choi, Taekyung Kim, Changick Kim
ICCV, 2019
arXiv

We propose a novel framework consisting of two components: Target-Guided and Cycle-Free Data Augmentation and Self-Ensembling algorithm

Self-Training and Adversarial Background Regularization for Unsupervised Domain Adaptive One-Stage Object Detection
Seunghyeon Kim, Jaehoon Choi, Taekyung Kim, Changick Kim
ICCV, 2019   (Oral)
arXiv

We introduce a weak self-training (WST) method and adversarial background score regularization (BSR) for domain adaptive one-stage object detection.

Pseudo-Labeling Curriculum for Unsueprvised Domain Adaptation
Jaehoon Choi, Minki Jeong, Taekyung Kim, Changick Kim
BMVC, 2019
arXiv

We propose a pseudo-labeling curriculum based on a density-based clustering algorithm.
