Background

Hyperspectral imaging (HSI) is a powerful technique capable of obtaining both spatial and spectral information from a target by combining conventional machine vision and point spectroscopy methods. During the past two decades, the HSI technologies have found numerous successful applications for food and agriculture. Owing to growth in data, advances in machine learning algorithms and software, and increased computing power, artificial intelligence (AI) is currently driving a new wave of innovation that is poised to revolutionize many industries. Sensing technologies in various disciplines are becoming one of primary frontiers for the AI-driven developments and transformations. By leveraging the combination of the HSI and learning-based AI techniques, it is promising to accomplish novel sensing applications with measurement capabilities and accuracies that were not possible in the past.


This Research Topic intends to collect papers that highlight recent advances in research and development of AI-based hyperspectral imaging methodologies and their applications in the food and agricultural areas. Recently, miniature imaging spectrographs/spectrometers, all-in-one small hyperspectral cameras, and snapshot hyperspectral imagers are commercially available, which make it possible to develop compact and portable imaging systems and devices that can be used in confined space (e.g., overhead imaging in plant growth chambers) and field applications (e.g., crop health/disease sensing using drones or ground platforms). Learning-based data analysis methods, along with high-performance computing, open a new avenue to process hyperspectral images for classification and regression purposes. Integration of AI capabilities through machine learning into hyperspectral imaging systems is becoming a new axis to develop novel smart sensing devices and instruments. Articles presenting the development of compact and portable spectral imaging systems, multimodal hyperspectral imaging and data fusion methods, advanced machine learning and deep learning algorithms for hyperspectral data analysis, embedded AI techniques for real-time inspections, as well as AI-based hyperspectral applications for food, precision agriculture, and high-throughput phenotyping are of particular interest.

This Research Topic welcomes Original Research, Review, Mini Review, and Perspective manuscripts on themes including but not limited to:
• Compact and portable hyperspectral and multispectral systems and devices for smart sensing

Frequently asked questions

  • Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

    Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

  • The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

    Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

  • As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

    A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

  • Each Research Topic must be approved by the specialty chief editor, and it falls under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

    In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

  • Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

    As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

    Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

     

  • Frontiers offers multiple article types, but it will depend on the field and section journals in which the Research Topic will be featured. The available article types for a Research Topic will appear in the drop-down menu during the submission process.
