Special Issue Information

Dear Colleagues,

Hyperspectral image (HSI) processing is one of the cutting-edge fields in remote sensing (RS), with many applications in precision agriculture, Earth observation, environmental monitoring, resource exploration and many more. As the demand for robust and precise HSI processing tools and techniques has been increasing in recent years, a wide number of studies have introduced machine learning (ML) techniques alongside chemometrics and pre-processing techniques, multivariate statistical data analysis tools and radiative transfer modeling to improve HSI quality and advance feature extraction and classification for both in-lab and/or field applications.

This Special Issue aims to compile studies covering different aspects of HSI processing algorithms and workflows that can enhance the spatial and/or spectral information contained across the HSI, and hence studies discussion pre-processing, calibration (geometric and/or radiometric) and radiative transfer modeling techniques are welcome. Newly proposed object/pattern recognition and classification algorithms, along with advanced ML and artificial intelligence (AI) approaches, can also be hosted in this Special Issue.

Articles may address, but are not limited to, the following HSI-related topics:

  • Precision agriculture
  • Earth observation
  • Environmental monitoring
  • Resource exploration
  • Data fusion
  • Drone photogrammetry
  • Soil research
  • Water research

The interference of background noise leads to the extremely high spatial complexity of hyperspectral data. Sensitive band selecting is an important task to minimize or eliminate the influence of non-target elements. In this study, Taylor expansion is innovatively used to identify core wavelengths/bands of hyperspectral data. Unlike other traditional methods, this proposed Taylor-CC method considers more local and global information of spectral function to estimate the linear/nonlinear correlation between two wavelengths. Using samples of hyperspectral data with a wavelength range of 350–2500 nm and SPAD for Camellia oleifera, this Taylor-CC method is compared with the traditional PCC method derived from the Pearson correlation coefficient. Using the 240 samples with their different 57 core wavelengths identified by the Taylor-CC method and PCC method, three machine models (i.e., random forest-RF, linear regression-LR, and artificial neural network-ANN) are trained to compare their performances. Their results show that the correlation matrix from the Taylor-CC method represents a clear diagonal pattern with near zero values at most locations away from the diagonal, and all three models confirm that the Taylor-CC method is superior to the PCC method. Moreover, the SPAD spectral response relationship based on machine learning algorithms is constructed, and ANN is the best prediction performance among the three models when using the core wavelengths identified by the Taylor-CC method. The Taylor-CC method proposed in this study not only lays a mathematical foundation for the next analysis of the response mechanism between spectral characteristics and nutrient content of Camellia leaf, but also provides a new idea for the correlation analysis of adjacent spectral bands for hyperspectral signals in many applications.

Hyperspectral image (HSI) super-resolution (SR) is a classical computer vision task that aims to accomplish the conversion of images from lower to higher resolutions. With the booming development of deep learning (DL) technology, more and more researchers are dedicated to the research of image SR techniques based on DL and have made remarkable progress. However, no scholar has provided a comprehensive review of the field. As a response, in this paper we aim to supply a comprehensive summary of the DL-based SR techniques for HSI, including upsampling frameworks, upsampling methods, network design, loss functions, representative works with different strategies, and future directions, in which we design several sets of comparative experiments for the advantages and limitations of two-dimensional convolution and three-dimensional convolution in the field of HSI SR and analyze the experimental results in depth. In addition, the paper also briefly discusses the secondary foci such as common datasets, evaluation metrics, and traditional SR algorithms. To the best of our knowledge, this paper is the first review on DL-based HSI SR. Full article
