ClickAttention: Click Region Similarity Guided Interactive Segmentation

1 code implementation12 Aug 2024 Long Xu, Shanghong Li, Yongquan Chen, Junkang Chen, Rui Huang, Feng Wu

To address this issue, we propose a click attention algorithm that expands the influence range of positive clicks based on the similarity between positively-clicked regions and the whole input.

Contextual Modeling for 3D Dense Captioning on Point Clouds

no code implementations8 Oct 2022 Yufeng Zhong, Long Xu, Jiebo Luo, Lin Ma

With such global and local contextual modeling strategies, our proposed model can effectively characterize the object representations and contextual information and thereby generate comprehensive and detailed descriptions of the located objects.

Deep Learning Eliminates Massive Dust Storms from Images of Tianwen-1

no code implementations21 Jun 2022 Hongyu Li, Jia Li, Xin Ren, Long Xu

Inspired by the haze formation process on Earth, we formulate a similar visual degradation process on clean images and synthesize dusty images sharing a similar feature distribution with realistic dusty images.

Complementary Feature Enhanced Network with Vision Transformer for Image Dehazing

1 code implementation15 Sep 2021 Dong Zhao, Jia Li, Hongyu Li, Long Xu

In this paper, firstly, we propose a new complementary feature enhanced framework, in which the complementary features are learned by several complementary subtasks and then together serve to boost the performance of the primary task.

Image Quality Assessment Guided Deep Neural Networks Training

3 code implementations13 Aug 2017 Zhuo Chen, Weisi Lin, Shiqi Wang, Long Xu, Leida Li

For many computer vision problems, the deep neural networks are trained and validated based on the assumption that the input images are pristine (i. e., artifact-free).
