Progressive Random Convolutions for Single Domain Generalization

no code implementations CVPR 2023 Seokeon Choi, Debasmit Das, Sungha Choi, Seunghan Yang, Hyunsin Park, Sungrack Yun

Single domain generalization aims to train a generalizable model with only one source domain to perform well on arbitrary unseen target domains.

Improving Test-Time Adaptation via Shift-agnostic Weight Regularization and Nearest Source Prototypes

no code implementations24 Jul 2022 Sungha Choi, Seunghan Yang, Seokeon Choi, Sungrack Yun

This paper proposes a novel test-time adaptation strategy that adjusts the model pre-trained on the source domain using only unlabeled online data from the target domain to alleviate the performance degradation due to the distribution shift between the source and target domains.

Learning to Discriminate Information for Online Action Detection: Analysis and Application

no code implementations8 Sep 2021 Sumin Lee, Hyunjun Eun, Jinyoung Moon, Seokeon Choi, Yoonhyung Kim, Chanho Jung, Changick Kim

To overcome this problem, we propose a novel recurrent unit, named Information Discrimination Unit (IDU), which explicitly discriminates the information relevancy between an ongoing action and others to decide whether to accumulate the input information.

Few-shot Open-set Recognition by Transformation Consistency

1 code implementation CVPR 2021 Minki Jeong, Seokeon Choi, Changick Kim

Based on the transformation consistency, our method measures the difference between the transformed prototypes and a modified prototype set.

Just a Few Points Are All You Need for Multi-View Stereo: A Novel Semi-Supervised Learning Method for Multi-View Stereo

no code implementations ICCV 2021 Taekyung Kim, Jaehoon Choi, Seokeon Choi, Dongki Jung, Changick Kim

We generate the spare ground truth of the DTU dataset for evaluation and extensive experiments verify that our SGT-MVSNet outperforms the state-of-the-art MVS methods on the sparse ground truth setting.

Meta Batch-Instance Normalization for Generalizable Person Re-Identification

1 code implementation CVPR 2021 Seokeon Choi, Taekyung Kim, Minki Jeong, Hyoungseob Park, Changick Kim

To this end, we combine learnable batch-instance normalization layers with meta-learning and investigate the challenging cases caused by both batch and instance normalization layers.

Robust Long-Term Object Tracking via Improved Discriminative Model Prediction

1 code implementation11 Aug 2020 Seokeon Choi, Junhyun Lee, Yunsung Lee, Alexander Hauptmann

We propose an improved discriminative model prediction method for robust long-term tracking based on a pre-trained short-term tracker.

RPM-Net: Robust Pixel-Level Matching Networks for Self-Supervised Video Object Segmentation

no code implementations29 Sep 2019 Youngeun Kim, Seokeon Choi, Hankyeol Lee, Taekyung Kim, Changick Kim

In this paper, we introduce a self-supervised approach for video object segmentation without human labeled data. Specifically, we present Robust Pixel-level Matching Net-works (RPM-Net), a novel deep architecture that matches pixels between adjacent frames, using only color information from unlabeled videos for training.

Learning to Align Multi-Camera Domains using Part-Aware Clustering for Unsupervised Video Person Re-Identification

no code implementations29 Sep 2019 Youngeun Kim, Seokeon Choi, Taekyung Kim, Sumin Lee, Changick Kim

Since the cost of labeling increases dramatically as the number of cameras increases, it is difficult to apply the re-identification algorithm to a large camera network.
