Special Issue Information
Dear Colleagues,
Hyperspectral images capture the spectral data for each pixel and provide very detailed characteristics of the materials within a scene. Hence, exploiting such detailed spectral information can open new possibilities in various domains. With the current sensor advances, we are facing exciting challenges concerned with efficient analysis of the highly dimensional image data in a plethora of real-life use cases, ranging from remote sensing, precision agriculture, chemistry, and biology to forensic applications, just to mention a few.
Classification and segmentation of hyperspectral imagery have been attracting research attention due to their wide practical applicability. By classification, we mean assigning class labels to specific hyperspectral pixels, while by segmentation, we mean finding the boundaries of the same-class objects in the entire input hyperspectral scene. Hence, segmentation involves classification of separate pixels in this case. Additionally, we can classify the full hyperspectral images (or patches) and assign specific class labels to them. Although these tasks are practically never the final ones in the hyperspectral processing chain, they clearly affect any further analysis steps. Therefore, improving the performance of hyperspectral classification and segmentation techniques is an extremely important research topic. We have been witnessing unprecedented success of deep learning in the field; however, there are still open issues to be carefully addressed in emerging applications—often related to the lack of ground-truth data (or its limited availability). Classical image analysis and machine learning algorithms are still of very high research interest as well.
The aim of this Special Issue is to gather and present recent advances in hyperspectral image classification and segmentation. The core themes of this topic cover all steps of the data processing pipeline, from its acquisition to final analysis and understanding, with special emphasis put on classification and segmentation. The themes of the Special Issue include but are not limited to:
- Hyperspectral data reduction in classification and segmentation tasks;
- Feature extraction and learning for accurate classification and segmentation;
- Classification and segmentation of hyperspectral images: algorithms and tools;
