Special Issue Information

Dear Colleagues,

Current advancements in sensor technology bring new possibilities in multi- and hyperspectral imaging. Real-life use cases which can benefit from such imagery span various domains, including precision agriculture, chemistry, biology, medicine, land cover applications, management of natural resources, detecting natural disasters, and more. To extract value from the detailed information available in up to hundreds of spectral bands in the electromagnetic spectrum, researchers have been designing a range of image-processing- and machine-learning-powered approaches toward efficient processing of such data. To this end, multi/hyperspectral analysis has bloomed and become an exciting research area which can enable faster adoption of this technology in practice, also when deployed in hardware-constrained and extreme execution environments, e.g., on board of imaging satellites.

The aim of this Special Issue is to gather and present recent advances in multi- and hyperspectral image analysis. The core themes of this topic cover all steps of the data processing pipeline, from its acquisition to final analysis and understanding. These themes include but are not limited to:

  • Pre/post-processing of multi/hyperspectral images;
  • Band selection from multi/hyperspectral images;
  • Feature extraction and learning from multi/hyperspectral images;
  • Data fusion of high-dimensional data;
  • Spectral and spatial super-resolution;
  • Spectral unmixing;
  • Deep learning-powered algorithms for multi/hyperspectral data analysis;
  • Classification and segmentation of multi/hyperspectral images;
  • Multitemporal and multisensor analysis;
  • Event detection and tracking;
  • Prediction from multi/hyperspectral data;
  • Deployment of machine/deep learning-powered techniques for multi/hyperspectral data analysis in hardware-constrained environments;
  • Robustness of deep learning-powered techniques for multi/hyperspectral data analysis;
  • Concept drift in multi/hyperspectral data analysis.

Blue steel roof is advantageous for its low cost, durability, and ease of installation. It is generally used by industrial areas. The accurate and rapid mapping of blue steel roof is important for the preliminary assessment of inefficient industrial areas and is one of the key elements for quantifying environmental issues like urban heat islands. Here, the DeeplabV3+ semantic segmentation neural network based on GaoFen-2 images was used to analyze the quantity and spatial distribution of blue steel roofs in the Nanhai district, Foshan (including the towns of Shishan, Guicheng, Dali, and Lishui), which is the important manufacturing industry base of China. We found that: (1) the DeeplabV3+ performs well with an overall accuracy of 92%, higher than the maximum likelihood classification; (2) the distribution of blue steel roofs was not even across the whole study area, but they were evenly distributed within the town scale; and (3) strong positive correlation was observed between blue steel roofs area and industrial gross output. These results not only can be used to detect the inefficient industrial areas for regional planning but also provide fundamental data for studies of urban environmental issues. Full article
