Special Issue Information

Dear Colleagues,

Due to the growing effective model training strategies, availability of large-scale labeled data sets, and high-performance computational hardware, deep learning-based methods have recently been utilized in a wide range of applications, including remote sensing image analysis. In addition. deep learning models have emerged in recent years as a powerful solution for processing high dimensional and complex remote sensing data in a variety of tasks (classification, regression, forecasting, or clustering). Although these methods can handle massive amounts of data collected by remote sensors, they require a large number of high-quality reference data. The complexity and dimensionality of remote sensing data, which are substantial, multi-variate, noisy, and irregularly collected increase the challenges in applying deep learning techniques in different Earth Observation applications.

This Special Issue will publish review and research documents on advanced deep learning models, including but not limited to innovative CNN, graph, and vision transformer-based deep learning techniques for remote sensing applications, focusing on tasks that discuss the field's issues.

Potential topics of interest are listed below:

  • Deep learning-based remote sensing image processing (image classification, object detection, semantic segmentation, pan-sharpening, image enhancement, and change detection)
  • Unsupervised, semi-supervised, self-supervised, graph, adversarial, active, and transfer learning for dealing with scarcity and/or low-quality of data sets.
  • Knowledge acquisition of deep learning architectures and algorithms for remote sensing images
  • Novel benchmark datasets for remote sensing image interpretation
  • Vision Transformer (ViT) in remote sensing

Constructing a surface representation from the sparse point cloud of a satellite is an important task for satellite on-orbit services such as satellite docking and maintenance. In related studies on surface reconstruction from point clouds, implicit neural representations have gained popularity in learning-based 3D object reconstruction. When aiming for a satellite with a more complicated geometry and larger intra-class variance, existing implicit approaches cannot perform well. To solve the above contradictions and make effective use of implicit neural representations, we built a NASA3D dataset containing point clouds, watertight meshes, occupancy values, and corresponding points by using the 3D models on NASA’s official website. On the basis of NASA3D, we propose a novel network called GONet for a more detailed reconstruction of satellite grids. By designing an explicit-related implicit neural representation of the Grid Occupancy Field (GOF) and introducing it into GONet, we compensate for the lack of explicit supervision in existing point cloud surface reconstruction approaches. The GOF, together with the occupancy field (OF), serves as the supervised information for neural network learning. Learning the GOF strengthens GONet’s attention to the critical points of the surface extraction algorithm Marching Cubes; thus, it helps improve the reconstructed surface’s accuracy. In addition, GONet uses the same encoder and decoder as ConvONet but designs a novel Adaptive Feature Aggregation (AFA) module to achieve an adaptive fusion of planar and volume features. The insertion of AFA allows for the obtained implicit features to incorporate more geometric and volumetric information. Both visualization and quantitative experimental results demonstrate that our GONet could handle 3D satellite reconstruction work and outperform existing state-of-the-art methods by a significant margin. With a watertight mesh, our GONet achieves 5.507 CD-L1, 0.8821 F-score, and 68.86% IoU, which is equal to gains of 1.377, 0.0466, and 3.59% over the previous methods using NASA3D, respectively.
