Remote and intermittent seeps are difficult to monitor in the field, yet surface oil slicks can be observed by spaceborne synthetic aperture radar (SAR) because they reduce backscatter, creating potential for automatic mapping. In mapping tasks like segmentation, deep learning models excel, albeit needing large amounts of labeled images. To deal with the scarcity of labeled images, transfer learning is an approach which makes use of knowledge from related domains. In the case of oil slicks, differences between Sentinel-1 acquisition modes, such as the interferometric wide (IW) in the North Sea and extra wide (EW) in the Arctic, complicate direct model transfer. Here, we present a use case where transfer learning enhances the few-shot segmentation of natural oil slicks. We used labeled slicks in IW images in the North Sea to pretrain a series of DeepLabv3 and segment anything models (SAMs). These models were then fine-tuned on EW-labeled slicks from two documented Arctic seeps on which we have only limited observations. Our results show clear evidence that transfer learning improves segmentation, notably in challenging and noisy images. Few studies, if any, have addressed transfer learning between SAR acquisition modes. This work contributes to improved monitoring of poorly understood or yet undiscovered hydrocarbon seeps.","PeriodicalId":91017,"journal":{"name":"IEEE geoscience and remote sensing letters : a publication of the IEEE Geoscience and Remote Sensing Society","volume":"22 ","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2025-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11031417","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144331615","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, due to the large-scale variations and complex morphological features of IW objects, existing detection methods have limitations in cross-scale feature extraction and information fusion. To address the aforementioned issues, this letter proposes a cascade hybrid global adaptive feature fusion you only look once (CHGAFF-YOLO) model for ocean IW detection. First, we employ the HGNetV2 structure as the backbone network of YOLO to better capture global information and extract complex features in a lightweight manner. Second, we introduce a Cascade Hybrid Cross-head Attention Module (CHCAM), which integrates in-group cascade attention with cross-head parallel self-attention mechanisms to achieve optimized multiscale feature extraction and enhance global feature representation capability. Finally, we design a Four-Head Adaptive Feature Fusion Module (FHAFF), which dynamically fuses feature information from different scales by constructing four detection heads, further enhancing cross-scale information interaction. Extensive experimental results show that our method significantly outperforms existing approaches on both the Sentinel-1 synthetic aperture radar (SAR) and MODIS satellite IW remote sensing datasets.","PeriodicalId":91017,"journal":{"name":"IEEE geoscience and remote sensing letters : a publication of the IEEE Geoscience and Remote Sensing Society","volume":"22 ","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2025-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144331583","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We develop SAMSelect and show its use for marine scientists visually interpreting floating marine debris in Sentinel-2 imagery. These debris are notoriously difficult to visualize due to their compositional heterogeneity in medium-resolution imagery. Out of these difficulties, a visual interpretation of imagery showing marine debris remains a common practice by domain experts, who select bands and spectral indices on a case-by-case basis informed by common practices and heuristics. SAMSelect selects the band or index combination that achieves the best classification accuracy on a small annotated dataset through the segment anything model (SAM). Its central assumption is that the three-channel visualization achieves the most accurate segmentation results also provide good visual information for photointerpretation. We evaluate SAMSelect in three Sentinel-2 scenes containing generic marine debris in Accra, Ghana, and Durban, South Africa, and deployed plastic targets from the Plastic Litter Project (PLP). This reveals the potential of new previously unused band combinations (e.g., a normalized difference index (NDI) of B8, <inline-formula> <tex-math>${B}2$ </tex-math></inline-formula>), which demonstrate improved performance compared with literature-based indices.

Anomaly detection (AD) in multispectral imagery serves as a fundamental tool in this context. Deep-learning (DL)-based techniques are particularly effective at capturing the intricate spectral and spatial patterns of anomalies. This letter proposes a new AD technique called attention-based convolutional neural network (ACNN), designed to enhance AD performance in multispectral images of high spatial resolution for the detection of human-made constructions. The model integrates attention mechanisms to prioritize informative features while suppressing irrelevant background information, thereby improving sensitivity to subtle and rare anomalies. Experimental results on multispectral datasets from semi-natural ecosystems show that the proposed approach outperforms existing DL techniques in terms of detection accuracy. These findings highlight the potential of attention-based models as a robust framework for environmental monitoring and AD in complex remote sensing scenarios.","PeriodicalId":91017,"journal":{"name":"IEEE geoscience and remote sensing letters : a publication of the IEEE Geoscience and Remote Sensing Society","volume":"22 ","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2025-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11028595","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144314750","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such solutions have been mainly designed from a DL perspective by leveraging the training and validation stage on the use of typical norm-based cost functions. For going beyond the DL perspective, in this letter, we propose an SAR-based validation stage by using SAR assessing metrics in the design and hyperparameter selection of neural networks. In the first phase, SAR assessing metrics may be used only as validation metrics to highlight critical issues that cannot be spotted with standard image-processing quality metrics. In a second phase, the same SAR assessing metrics may be used directly for enhancing the DL solution by addressing specific issues that arose during the previous SAR-based validation stage. To this aim, three different DL SAR despeckling solutions and four different SAR assessing metrics have been considered. The outcome of this analysis shows the importance of including SAR knowledge in the training and validation stages of the design of a DL solution for SAR image despeckling.","PeriodicalId":91017,"journal":{"name":"IEEE geoscience and remote sensing letters : a publication of the IEEE Geoscience and Remote Sensing Society","volume":"22 ","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2025-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144314749","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

GF5-02, the successor to the GF5 satellite, was equipped with six advanced hyperspectral payloads. One of the most important payloads onboard the GF5-02 satellite, the advanced hyperspectral imager (AHSI) has a spatial resolution of 30 m, 330 bands in a spectral range of 380–2500 nm. The spectral resolution of the visible and near infrared (VNIR) and short-wave infrared (SWIR) bands are better than 5 and 10 nm, respectively. To analyze the spectral performance of the GF5-02 AHSI, an on-orbit spectral calibration method that utilizes atmospheric limb observations with an on-board calibration system was proposed in this letter. The on-orbit spectral calibration results were validated by atmospheric absorption features with synchronous measurements of surface reflectance and atmospheric parameters. For the GF5-02 AHSI, the shifts in the central wavelength of the VNIR band is 0.117nm, while the shifts in the full width at half maximum (FWHM) is 0.02 nm. In the SWIR band, these values are 0.25 nm for the central wavelength and 0.04 nm for the FWHM.

In this letter, we propose a mamba-wavelet cross-modal fusion network with graph pooling (MW-CMFNet) for HSI and LiDAR joint classification. First, a two-branch feature extraction (TBFE) is used to extract spatial and spectral features. Then, in order to dig deeper into the complementary information of different modalities and fully fuse them under the guidance of frequency-domain information, a mamba-wavelet cross-modal feature fusion (MW-CMFF) module is devised, it aims to utilize mamba’s outstanding long-range modeling ability to learn complementary information in the spatial and frequency domains, Finally, the graph pooling module is designed to sense the intrinsic dependencies of neighboring pixels and explore the importance difference of pixels, rather than assigning the same weight to different pixels.

To solve this problem, we propose an entropy-driven clustering and semantic association framework for cross-domain few-shot HSI classification (ECSA-FSL). We design a deep semantic association feature enhancement module (FEA), which first explores the potential semantic relationship between the source and target domains, and then constructs a cross-domain feature enhancement strategy to generate more discriminative features. In addition, we employ an entropy-driven clustering mechanism (EDC) to optimize the feature space distribution of the target domain. Our approach achieves remarkable classification accuracy with a small number of samples, particularly excelling in scenarios with high intraclass variability and limited training data.

The experimental results indicate that the vegetation-transmitted GNSS signal continues to conform to the characteristics of a Normal [right-hand circular polarization (RHCP)] and Weibull [left-hand circular polarization (LHCP)] distribution; however, significant variations are observed in the distribution parameters and the parameter value ranges.
