Modeling Weather Uncertainty for Multi-weather Co-Presence Estimation

no code implementations29 Mar 2024 Qi Bi, ShaoDi You, Theo Gevers

In this paper, we start with solid revisit of the physics definition of weather and how it can be described as a continuous machine learning and computer vision task.

Learning Generalized Segmentation for Foggy-scenes by Bi-directional Wavelet Guidance

1 code implementation Association for the Advancement of Artificial Intelligence (AAAI) 2024 Qi Bi, ShaoDi You, Theo Gevers

We argue that an ideal segmentation model that can be well generalized to foggy-scenes need to simultaneously enhance the content, de-correlate the urban-scene style and de-correlate the fog style.

GOOD: Towards Domain Generalized Orientated Object Detection

no code implementations20 Feb 2024 Qi Bi, Beichen Zhou, Jingjun Yi, Wei Ji, Haolan Zhan, Gui-Song Xia

In this paper, we propose the task of domain generalized oriented object detection, which intends to explore the generalization of oriented object detectors on arbitrary unseen target domains.

Cross-Level Multi-Instance Distillation for Self-Supervised Fine-Grained Visual Categorization

no code implementations16 Jan 2024 Qi Bi, Wei Ji, Jingjun Yi, Haolan Zhan, Gui-Song Xia

To comprehensively learn the relation between informative patches and fine-grained semantics, the multi-instance knowledge distillation is implemented on both the region/image crop pairs from the teacher and student net, and the region-image crops inside the teacher / student net, which we term as intra-level multi-instance distillation and inter-level multi-instance distillation.

Interactive Learning of Intrinsic and Extrinsic Properties for All-day Semantic Segmentation

1 code implementation IEEE Transactions on Image Processing 2023 Qi Bi, ShaoDi You, Theo Gevers

In this paper, in contrast to existing methods, we tackle this challenge from the perspective of image formulation itself, where the image appearance is determined by both intrinsic (e. g., semantic category, structure) and extrinsic (e. g., lighting) properties.

Learning Content-enhanced Mask Transformer for Domain Generalized Urban-Scene Segmentation

1 code implementation1 Jul 2023 Qi Bi, ShaoDi You, Theo Gevers

Unlike domain gap challenges, USSS is unique in that the semantic categories are often similar in different urban scenes, while the styles can vary significantly due to changes in urban landscapes, weather conditions, lighting, and other factors.

Temporal Cue Guided Video Highlight Detection With Low-Rank Audio-Visual Fusion

no code implementations ICCV 2021 Qinghao Ye, Xiyue Shen, Yuan Gao, ZiRui Wang, Qi Bi, Ping Li, Guang Yang

Video highlight detection plays an increasingly important role in social media content filtering, however, it remains highly challenging to develop automated video highlight detection methods because of the lack of temporal annotations (i. e., where the highlight moments are in long videos) for supervised learning.

Building change detection based on multi-scale filtering and grid partition

no code implementations22 Aug 2019 Qi Bi, Kun Qin, Han Zhang, Wenjun Han, Zhili Li, Kai Xu

Exhaustive experiments indicate that the proposed method can detect building change types directly and outperform the current multi-index learning method.

Multiple instance dense connected convolution neural network for aerial image scene classification

no code implementations22 Aug 2019 Qi Bi, Kun Qin, Zhili Li, Han Zhang, Kai Xu

While the current convolution neural network tends to extract global features and global semantic information in a scene, the geo-spatial objects can be located at anywhere in an aerial image scene and their spatial arrangement tends to be more complicated.
