Low-Resource Vision Challenges for Foundation Models

no code implementations9 Jan 2024 Yunhua Zhang, Hazel Doughty, Cees G. M. Snoek

Low-resource settings are well-established in natural language processing, where many languages lack sufficient data for deep learning at scale.

Day2Dark: Pseudo-Supervised Activity Recognition beyond Silent Daylight

no code implementations5 Dec 2022 Yunhua Zhang, Hazel Doughty, Cees G. M. Snoek

The main causes are the limited availability of labeled dark videos to learn from, as well as the distribution shift towards the lower color contrast at test-time.

TANet: Transformer-based Asymmetric Network for RGB-D Salient Object Detection

1 code implementation4 Jul 2022 Chang Liu, Gang Yang, Shuo Wang, Hangxu Wang, Yunhua Zhang, Yutao Wang

We employ the powerful feature extraction capability of Transformer (PVTv2) to extract global semantic information from RGB data and design a lightweight CNN backbone (LWDepthNet) to extract spatial structure information from depth data without pre-training.

Audio-Adaptive Activity Recognition Across Video Domains

1 code implementation CVPR 2022 Yunhua Zhang, Hazel Doughty, Ling Shao, Cees G. M. Snoek

This paper strives for activity recognition under domain shift, for example caused by change of scenery or camera viewpoint.

Repetitive Activity Counting by Sight and Sound

1 code implementation CVPR 2021 Yunhua Zhang, Ling Shao, Cees G. M. Snoek

We also introduce a variant of this dataset for repetition counting under challenging vision conditions.

High-Performance Long-Term Tracking with Meta-Updater

2 code implementations CVPR 2020 Kenan Dai, Yunhua Zhang, Dong Wang, Jianhua Li, Huchuan Lu, Xiaoyun Yang

Most top-ranked long-term trackers adopt the offline-trained Siamese architectures, thus, they cannot benefit from great progress of short-term trackers with online update.

Learning regression and verification networks for long-term visual tracking

3 code implementations12 Sep 2018 Yunhua Zhang, Dong Wang, Lijun Wang, Jinqing Qi, Huchuan Lu

Compared with short-term tracking, the long-term tracking task requires determining the tracked object is present or absent, and then estimating the accurate bounding box if present or conducting image-wide re-detection if absent.

Structured Siamese Network for Real-Time Visual Tracking

no code implementations ECCV 2018 Yunhua Zhang, Lijun Wang, Jinqing Qi, Dong Wang, Mengyang Feng, Huchuan Lu

In this paper, we circumvent this issue by proposing a local structure learning method, which simultaneously considers the local patterns of the target and their structural relationships for more accurate target tracking.
