Dual Refinement Underwater Object Detection Network

no code implementations ECCV 2020 Baojie Fan, Wei Chen, Yang Cong, Jiandong Tian

Due to the complex underwater environment, underwater imaging often encounters some problems such as blur, scale variation, color shift, and texture distortion.

EasyTrack: Efficient and Compact One-stream 3D Point Clouds Tracker

no code implementations9 Apr 2024 Baojie Fan, Wuyang Zhou, Kai Wang, Shijun Zhou, Fengyu Xu, Jiandong Tian

Most of 3D single object trackers (SOT) in point clouds follow the two-stream multi-stage 3D Siamese or motion tracking paradigms, which process the template and search area point clouds with two parallel branches, built on supervised point cloud backbones.

Robust 3D Tracking with Quality-Aware Shape Completion

no code implementations17 Dec 2023 Jingwen Zhang, Zikun Zhou, Guangming Lu, Jiandong Tian, Wenjie Pei

Considering that, we propose to construct a synthetic target representation composed of dense and complete point clouds depicting the target shape precisely by shape completion for robust 3D tracking.

SA$^2$VP: Spatially Aligned-and-Adapted Visual Prompt

1 code implementation16 Dec 2023 Wenjie Pei, Tongqi Xia, Fanglin Chen, Jinsong Li, Jiandong Tian, Guangming Lu

Typical methods for visual prompt tuning follow the sequential modeling paradigm stemming from NLP, which represents an input image as a flattened sequence of token embeddings and then learns a set of unordered parameterized tokens prefixed to the sequence representation as the visual prompts for task adaptation of large vision models.

D$^2$ST-Adapter: Disentangled-and-Deformable Spatio-Temporal Adapter for Few-shot Action Recognition

1 code implementation3 Dec 2023 Wenjie Pei, Qizhong Tan, Guangming Lu, Jiandong Tian

In particular, we devise the anisotropic Deformable Spatio-Temporal Attention module as the core component of D$^2$ST-Adapter, which can be tailored with anisotropic sampling densities along spatial and temporal domains to learn spatial and temporal features specifically in corresponding pathways, allowing our D$^2$ST-Adapter to encode features in a global view in 3D spatio-temporal space while maintaining a lightweight design.

Activating the Discriminability of Novel Classes for Few-shot Segmentation

no code implementations2 Dec 2022 Dianwen Mei, Wei Zhuo, Jiandong Tian, Guangming Lu, Wenjie Pei

To circumvent these two challenges, we propose to activate the discriminability of novel classes explicitly in both the feature encoding stage and the prediction stage for segmentation.

Few-Shot Object Detection by Knowledge Distillation Using Bag-of-Visual-Words Representations

no code implementations25 Jul 2022 Wenjie Pei, Shuang Wu, Dianwen Mei, Fanglin Chen, Jiandong Tian, Guangming Lu

In this work we design a novel knowledge distillation framework to guide the learning of the object detector and thereby restrain the overfitting in both the pre-training stage on base classes and fine-tuning stage on novel classes.

Multi-Faceted Distillation of Base-Novel Commonality for Few-shot Object Detection

1 code implementation22 Jul 2022 Shuang Wu, Wenjie Pei, Dianwen Mei, Fanglin Chen, Jiandong Tian, Guangming Lu

Most of existing methods for few-shot object detection follow the fine-tuning paradigm, which potentially assumes that the class-agnostic generalizable knowledge can be learned and transferred implicitly from base classes with abundant samples to novel classes with limited samples via such a two-stage training strategy.

Tracking-by-Counting: Using Network Flows on Crowd Density Maps for Tracking Multiple Targets

no code implementations18 Jul 2020 Weihong Ren, Xinchao Wang, Jiandong Tian, Yandong Tang, Antoni B. Chan

State-of-the-art multi-object tracking~(MOT) methods follow the tracking-by-detection paradigm, where object trajectories are obtained by associating per-frame outputs of object detectors.

Depth and Image Restoration From Light Field in a Scattering Medium

no code implementations ICCV 2017 Jiandong Tian, Zachary Murez, Tong Cui, Zhen Zhang, David Kriegman, Ravi Ramamoorthi

First, we present a new single image restoration algorithm which removes backscatter and attenuation from images better than existing methods, and apply it to each view in the light field.

RGBD Salient Object Detection via Deep Fusion

no code implementations12 Jul 2016 Liangqiong Qu, Shengfeng He, Jiawei Zhang, Jiandong Tian, Yandong Tang, Qingxiong Yang

Numerous efforts have been made to design different low level saliency cues for the RGBD saliency detection, such as color or depth contrast features, background and color compactness priors.

Pixel-wise Orthogonal Decomposition for Color Illumination Invariant and Shadow-free Image

no code implementations30 Jun 2014 Liangqiong Qu, Jiandong Tian, Zhi Han, Yandong Tang

In this paper, we propose a novel, effective and fast method to obtain a color illumination invariant and shadow-free image from a single outdoor image.
