Tracking by Natural Language Specification with Long Short-term Context Decoupling

no code implementations ICCV 2023 Ding Ma, Xiangqian Wu

The main challenge of Tracking by Natural Language Specification (TNL) is to predict the movement of the target object by giving two heterogeneous information, e. g., one is the static description of the main characteristics of a video contained in the textual query, i. e., long-term context; the other one is an image patch containing the object and its surroundings cropped from the current frame, i. e., the search area.

CapsuleRRT: Relationships-Aware Regression Tracking via Capsules

no code implementations CVPR 2021 Ding Ma, Xiangqian Wu

Regression tracking has gained more and more attention thanks to its easy-to-implement characteristics, while existing regression trackers rarely consider the relationships between the object parts and the complete object.

Pyramid Feature Attention Network for Saliency detection

6 code implementations CVPR 2019 Ting Zhao, Xiangqian Wu

To solve this problem, we propose Pyramid Feature Attention network to focus on effective high-level context features and low-level spatial structural features.

TCDCaps: Visual Tracking via Cascaded Dense Capsules

no code implementations26 Feb 2019 Ding Ma, Xiangqian Wu

The critical challenge in tracking-by-detection framework is how to avoid drift problem during online learning, where the robust features for a variety of appearance changes are difficult to be learned and a reasonable intersection over union (IoU) threshold that defines the true/false positives is hard to set.

Saliency Detection via Combining Region-Level and Pixel-Level Predictions with CNNs

no code implementations18 Aug 2016 Youbao Tang, Xiangqian Wu

This paper proposes a novel saliency detection method by combining region-level saliency estimation and pixel-level saliency prediction with CNNs (denoted as CRPSD).
