Weakly Supervised Semantic Segmentation for Driving Scenes

1 code implementation21 Dec 2023 Dongseob Kim, Seungho Lee, Junsuk Choe, Hyunjung Shim

Notably, the proposed method achieves 51. 8\% mIoU on the Cityscapes test dataset, showcasing its potential as a strong WSSS baseline on driving scene datasets.

Neglected Free Lunch -- Learning Image Classifiers Using Annotation Byproducts

3 code implementations30 Mar 2023 Dongyoon Han, Junsuk Choe, Seonghyeok Chun, John Joon Young Chung, Minsuk Chang, Sangdoo Yun, Jean Y. Song, Seong Joon Oh

We refer to the new paradigm of training models with annotation byproducts as learning using annotation byproducts (LUAB).

Weakly Supervised Semantic Segmentation using Out-of-Distribution Data

1 code implementation CVPR 2022 Jungbeom Lee, Seong Joon Oh, Sangdoo Yun, Junsuk Choe, Eunji Kim, Sungroh Yoon

However, training on class labels only, classifiers suffer from the spurious correlation between foreground and background cues (e. g. train and rail), fundamentally bounding the performance of WSSS.

Normalization Matters in Weakly Supervised Object Localization

1 code implementation ICCV 2021 Jeesoo Kim, Junsuk Choe, Sangdoo Yun, Nojun Kwak

Weakly-supervised object localization (WSOL) enables finding an object using a dataset without any localization information.

Keep CALM and Improve Visual Feature Attribution

1 code implementation ICCV 2021 Jae Myung Kim, Junsuk Choe, Zeynep Akata, Seong Joon Oh

The class activation mapping, or CAM, has been the cornerstone of feature attribution methods for multiple vision tasks.

Rethinking Spatial Dimensions of Vision Transformers

10 code implementations ICCV 2021 Byeongho Heo, Sangdoo Yun, Dongyoon Han, Sanghyuk Chun, Junsuk Choe, Seong Joon Oh

We empirically show that such a spatial dimension reduction is beneficial to a transformer architecture as well, and propose a novel Pooling-based Vision Transformer (PiT) upon the original ViT model.

Contrastive Attention Maps for Self-Supervised Co-Localization

no code implementations ICCV 2021 Minsong Ki, Youngjung Uh, Junsuk Choe, Hyeran Byun

The goal of unsupervised co-localization is to locate the object in a scene under the assumptions that 1) the dataset consists of only one superclass, e. g., birds, and 2) there are no human-annotated labels in the dataset.

Evaluation for Weakly Supervised Object Localization: Protocol, Metrics, and Datasets

2 code implementations8 Jul 2020 Junsuk Choe, Seong Joon Oh, Sanghyuk Chun, Seungho Lee, Zeynep Akata, Hyunjung Shim

In this paper, we argue that WSOL task is ill-posed with only image-level labels, and propose a new evaluation protocol where full supervision is limited to only a small held-out set not overlapping with the test set.

An Empirical Evaluation on Robustness and Uncertainty of Regularization Methods

no code implementations9 Mar 2020 Sanghyuk Chun, Seong Joon Oh, Sangdoo Yun, Dongyoon Han, Junsuk Choe, Youngjoon Yoo

Despite apparent human-level performances of deep neural networks (DNN), they behave fundamentally differently from humans.

Attention-based Dropout Layer for Weakly Supervised Object Localization

1 code implementation CVPR 2019 Junsuk Choe, Hyunjung Shim

Weakly Supervised Object Localization (WSOL) techniques learn the object location only using image-level labels, without location annotations.

Generative Adversarial Networks for Unsupervised Object Co-localization

no code implementations1 Jun 2018 Junsuk Choe, Joo Hyun Park, Hyunjung Shim

Our important finding is that high image diversity of GAN, which is a main goal in GAN research, is ironically disadvantageous for object localization, because such discriminators focus not only on the target object, but also on the various objects, such as background objects.
