Generating representative samples for few-shot classification

J Xu, H Le - Proceedings of the IEEE/CVF Conference on …, 2022 - openaccess.thecvf.com
Few-shot learning (FSL) aims to learn new categories with a few visual samples per class.
Few-shot class representations are often biased due to data scarcity. To mitigate this issue …

From shadow generation to shadow removal

Z Liu, H Yin, X Wu, Z Wu, Y Mi… - Proceedings of the …, 2021 - openaccess.thecvf.com
Shadow removal is a computer-vision task that aims to restore the image content in shadow
regions. While almost all recent shadow-removal methods require shadow-free images for …

Shadow removal via shadow image decomposition

H Le, D Samaras - Proceedings of the IEEE/CVF …, 2019 - openaccess.thecvf.com
We propose a novel deep learning method for shadow removal. Inspired by physical models
of shadow formation, we use a linear illumination transformation to model the shadow effects …

Zero-shot object counting

J Xu, H Le, V Nguyen, V Ranjan… - Proceedings of the …, 2023 - openaccess.thecvf.com
Class-agnostic object counting aims to count object instances of an arbitrary class at test
time. It is challenging but also enables many potential applications. Current methods require …

Deep feature factorization for concept discovery

E Collins, R Achanta… - Proceedings of the …, 2018 - openaccess.thecvf.com
Abstract We propose Deep Feature Factorization (DFF), a method capable of localizing
similar semantic concepts within an image or a set of images. We use DFF to gain insight …

Generating features with increased crop-related diversity for few-shot object detection

J Xu, H Le, D Samaras - … of the IEEE/CVF Conference on …, 2023 - openaccess.thecvf.com
Two-stage object detectors generate object proposals and classify them to detect objects in
images. These proposals often do not perfectly contain the objects but overlap with them in …

Beyond Pixels: Semi-Supervised Semantic Segmentation with a Multi-scale Patch-based Multi-Label Classifier

P Howlader, S Das, H Le, D Samaras - European Conference on …, 2025 - Springer
Incorporating pixel contextual information is critical for accurate segmentation. In this paper,
we show that an effective way to incorporate contextual information is through a patch-based …

Self-supervised co-salient object detection via feature correspondences at multiple scales

S Chakraborty, D Samaras - European Conference on Computer Vision, 2025 - Springer
Our paper introduces a novel two-stage self-supervised approach for detecting co-occurring
salient objects (CoSOD) in image groups without requiring segmentation annotations …
