OV-VG: A Benchmark for Open-Vocabulary Visual Grounding

1 code implementation22 Oct 2023 Chunlei Wang, Wenquan Feng, Xiangtai Li, Guangliang Cheng, Shuchang Lyu, Binghao Liu, Lijiang Chen, Qi Zhao

While current foundational models excel at various visual language tasks, there's a noticeable absence of models specifically tailored for open-vocabulary visual grounding.

Self-Training Guided Disentangled Adaptation for Cross-Domain Remote Sensing Image Semantic Segmentation

1 code implementation13 Jan 2023 Qi Zhao, Shuchang Lyu, Binghao Liu, Lijiang Chen, Hongbo Zhao

We first propose source student backbone and target student backbone to respectively extract the source-style and target-style feature for both source and target images.

MMOTU: A Multi-Modality Ovarian Tumor Ultrasound Image Dataset for Unsupervised Cross-Domain Semantic Segmentation

1 code implementation14 Jul 2022 Qi Zhao, Shuchang Lyu, Wenpei Bai, Linghan Cai, Binghao Liu, Guangliang Cheng, Meijing Wu, Xiubo Sang, Min Yang, Lijiang Chen

To solve this problem, we propose a Multi-Modality Ovarian Tumor Ultrasound (MMOTU) image dataset containing 1469 2d ultrasound images and 170 contrast enhanced ultrasonography (CEUS) images with pixel-wise and global-wise annotations.

Attention-based Feature Decomposition-Reconstruction Network for Scene Text Detection

no code implementations29 Nov 2021 Qi Zhao, YuFei Wang, Shuchang Lyu, Lijiang Chen

In this paper, we propose attention-based feature decomposition-reconstruction network for scene text detection, which utilizes contextual information and low-level feature to enhance the performance of segmentation-based text detector.

MGML: Multi-Granularity Multi-Level Feature Ensemble Network for Remote Sensing Scene Classification

no code implementations29 Dec 2020 Qi Zhao, Shuchang Lyu, Yuewen Li, Yujing Ma, Lijiang Chen

To avoid the interference from confusing information, we propose Multi-granularity Multi-Level Feature Ensemble Module (MGML-FEM) which can provide diverse predictions by full-channel feature generator (FC-FG).

Point Context: An Effective Shape Descriptor for RST-invariant Trajectory Recognition

no code implementations22 Jan 2015 Xingyu Wu, Xia Mao, Lijiang Chen, Yuli Xue, Angelo Compare

Secondly, the shape context is nonlinearly mapped to a subspace by kernel nonparametric discriminant analysis (KNDA) to get a compact feature representation, and thus a trajectory is projected to a single point in a low-dimensional feature space.

Translation

Machine Translation Model based on Non-parallel Corpus and Semi-supervised Transductive Learning

no code implementations22 May 2014 Lijiang Chen

Although the parallel corpus has an irreplaceable role in machine translation, its scale and coverage is still beyond the actual needs.
