Existing models face core challenges such as feature degradation of small objects, extreme scale variations, and intricate, dynamic backgrounds. To address these issues, this article proposes a triple dynamic optimization framework for remote sensing target detection (TDO-YOLO). First, construct the deformable reparameterized feature module, which utilizes multibranch feature fusion and structural reparameterization techniques to achieve refined capture of tiny and multiscale targets. Second, we design an adaptive receptive field fusion (ARFF) module that overcomes fixed receptive field limitations in traditional convolutions through parallel multiscale kernel extraction and geometry-aware feature reorganization, significantly improving multiscale object detection accuracy. Third, we propose a convolutional dynamic position-encoding residual attention mechanism, leveraging long-range dependency modeling and background suppression to effectively mitigate complex background interference and reduce false detection rates. Finally, we introduce a multiscale-aware IoU loss function specifically designed for remote sensing images, incorporating multiscale perception mechanisms and dynamic weighting to enhance detection precision.

Furthermore, many methods insufficiently exploit high-frequency details and lack the ability to effectively model both global context and local structures. To address these challenges, this article proposes an edge-enhanced SR framework for RS images. A more realistic degradation model is constructed by estimating blur kernels from real LR images. The edge-enhanced and structure-aware generative adversarial network is designed, incorporating the edge priorenhancement module, the edge-aware local attention module, and the dynamic feature space attention module. The edge-guided loss is also introduced to enhance image sharpness and perceptual consistency.

Automated mapping approaches can leverage freely accessible satellite data to supplement navigational ice charts, improve operational forecasting, and produce high-resolution sea ice parameter estimates. The AI4Arctic dataset enables deep learning-based mapping using synthetic aperture radar (SAR), passive microwave (PM), and reanalysis data. However, SAR and PM can struggle to resolve ice features due to ambiguous textures, atmospheric effects, and sensor limitations. To provide complementary data, an 84-scene Visible Infrared Imager Radiometer Suite (VIIRS) dataset is co-registered with AI4Arctic to evaluate whether ice surface temperature (IST) measurements can improve estimation of sea ice concentration (SIC), stage of development, and floe size. Input- and feature-level fusion methods, based on the U-Net architecture, are explored. Models are evaluated using the SIC <italic>R</i><sup>2</sup> coefficient and SOD/FLOE F1-score, as well as predicted sea ice maps. In addition, an alternative SIC accuracy score is introduced to assist with evaluating marginal ice predictions. Incorporating IST improves performance across all models compared to the AI4Arctic baseline; this includes single-encoder, dual-encoder, and multidecoder U-Nets. Results highlight significant improvements in the prediction of open water under conditions with low-incidence angle, high atmospheric moisture, and wind roughening. Overall, the best performing dual-encoder model, DUE-Net-V, improves predictions by 2.18–5.01% across all metrics, relative to the baseline.

Domain adaptive methods require access to target data when aligning distributions between domains, while domain generalization methods allow models trained on the source domain to be immediately utilized in unknown domains, with a wider range of applicability. Currently, most domain generalization methods mainly focus on generating simulated samples related to the source domain and using some strategies, such as adversarial learning, to obtain domain-invariant features. Nevertheless, these methods fail to clearly distinguish domain-invariant features from domain-specific features, which makes the model prone to fitting specific features and makes it difficult to learn invariant features effectively. Inspired by disentangled representation learning, we propose a novel domain-invariant progressive enhancement network for cross-scene classification of HSI. First, a domain invariant progressive enhancement module is proposed, which is based on a frequency domain disentanglement layer to gradually separate domain invariant features from shallow to deep layers. Then, a re-entanglement module is carefully designed for deep fusion of original features and domain invariant features, thereby improving generalization ability. Finally, a frequency-aware feature aggregation module is constructed for more accurately extracting features that are conducive to classification. Some experiments carried out on three public datasets indicate that the proposed method outperforms some state-of-the-art approaches with a large margin.","PeriodicalId":13116,"journal":{"name":"IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing","volume":"18 ","pages":"24701-24715"},"PeriodicalIF":5.3,"publicationDate":"2025-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11164787","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145210069","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Existing CR methods heavily rely on image similarity metrics, such as peak signal-to-noise ratio and structural similarity index measure to evaluate the quality of CR results. However, due to factors including rapid changes in landforms and viewpoint differences between cloudy and reference images, image similarity metrics could be ineffective, even misleading. To address these challenges, this study investigates CR by evaluating whether CR algorithms effectively produce information beneficial for downstream tasks. We introduce CUHKCR-EXT, the first very-high-resolution CR dataset explicitly designed for post-CR downstream task performance assessment. Furthermore, we propose DFCFormer, a dynamic filter-based transformer that generates adaptive kernels conditioned on cloud characteristics, enabling more precise recovery across diverse cloud types within a unified framework. In addition, we design a feature alignment loss that enforces consistency between cloud-removed and reference features at the semantic level, which guides the model to retain landform-relevant information crucial for downstream analysis. Using scene classification as a representative downstream task, we conduct extensive experiments and evaluate performance using both image similarity and information loss metrics. The results demonstrate that the proposed method achieves strong performance across all evaluated metrics. More importantly, the improvements lie not only in image similarity but also in the preservation of task-relevant semantics, which enhances the effective quality of output images for downstream applications rather than merely their visual fidelity.","PeriodicalId":13116,"journal":{"name":"IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing","volume":"18 ","pages":"24531-24545"},"PeriodicalIF":5.3,"publicationDate":"2025-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11165130","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145210066","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Specifically, RRCA-Net incorporates reusable-convolution block (RuCB) in a recurrent manner without introducing extra parameters. With the help of the repetitive iteration in RuCB, the high-level information of small targets in the deep layers can be well maintained and further refined. Then, a dual interactive attention aggregation module is proposed to promote the mutual enhancement and fusion of refined information. In this way, RRCA-Net can both achieve high-level feature refinement and enhance the correlation of contextual information between adjacent layers. Moreover, to achieve steady convergence, we design a target characteristic inspired loss function (DpT-k loss) by integrating physical and mathematical constraints. Experimental results on three benchmark datasets (e.g., NUAA-SIRST, IRSTD-1k, DenseSIRST) demonstrate that our RRCA-Net can achieve comparable performance to the state-of-the-art methods while maintaining a small number of parameters, and act as a plug and play module to introduce consistent performance improvement for several popular IRSTD methods.","PeriodicalId":13116,"journal":{"name":"IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing","volume":"18 ","pages":"24632-24646"},"PeriodicalIF":5.3,"publicationDate":"2025-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11164892","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145210145","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While satellite observations provide high spatial resolution temperature data, cloud contamination creates gaps that require filling methods–a process that can bias warming trend calculations. Traditional gap-filling approaches, though accurate for absolute temperatures, consistently underestimate warming trends. This study presents a new data assimilation method that integrates moderate-resolution imaging spectroradiometer derived air temperatures with ERA5-Land reanalysis data to achieve unbiased warming trend detection while maintaining high spatial resolution. We validate our method against weather station data on the Tibetan Plateau (TP) and compare it with four mainstream gap-filling approaches: 1) temporal, 2) spatial, 3) spatio-temporal, and 4) multisource fusion-based methods. Our results show that while all methods, including ours, perform similarly in terms of absolute temperature accuracy (with root-mean-square error around 1.66 °C and R around 0.99), a critical difference emerges in warming trend estimation. Traditional gap-filling methods show negative biases in warming trends, but our assimilation-based approach almost completely eliminates these biases when validated against both station-level data and elevation-binned averages. The integrated air temperature for the TP reveals significant warming patterns, particularly in glacier regions, although the overall warming rate (0.022 °C/yr) is lower than that indicated by station data alone (0.026 °C/yr). This difference likely reflects the ability of our method to capture warming trends across the diverse terrain of the plateau, not just at station locations. This improvement in trend estimation, combined with the method’s ability to maintain high spatial resolution, represents a significant advance in the use of satellite-derived data for climate change analysis.","PeriodicalId":13116,"journal":{"name":"IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing","volume":"18 ","pages":"24924-24935"},"PeriodicalIF":5.3,"publicationDate":"2025-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11164928","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145255862","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
