Deep Semantic-Visual Alignment for Zero-Shot Remote Sensing Image Scene Classification

1 code implementation3 Feb 2024 Wenjia Xu, Jiuniu Wang, Zhiwei Wei, Mugen Peng, Yirong Wu

Besides, pioneer ZSL models use convolutional neural networks pre-trained on ImageNet, which focus on the main objects appearing in each image, neglecting the background context that also matters in RS scene classification.

Jointly Optimized Global-Local Visual Localization of UAVs

no code implementations12 Oct 2023 Haoling Li, Jiuniu Wang, Zhiwei Wei, Wenjia Xu

Our GLVL network is a two-stage visual localization approach, combining a large-scale retrieval module that finds similar regions with the UAV flight scene, and a fine-grained matching module that localizes the precise UAV coordinate, enabling real-time and precise localization.

Combining Supervised and Un-supervised Learning for Automatic Citrus Segmentation

no code implementations4 May 2021 Heqing Huang, Tongbin Huang, Zhen Li, Zhiwei Wei, Shilei Lv

Compared with most of the existing citrus segmentation methods, our method uses a small amount of supervised data and a large number of unsupervised data, while learning the pixel level location information and the temporal information of citrus changes to enhance the segmentation effect.

AMRNet: Chips Augmentation in Aerial Images Object Detection

no code implementations15 Sep 2020 Zhiwei Wei, Chenzhen Duan, Xinghao Song, Ye Tian, Hongpeng Wang

Specifically, we propose a scale adaptive module, which dynamically adjusts chip size to balance object scale, narrowing scale variation in training.
