Introduction: Multispectral and hyperspectral imaging have emerged as powerful tools in medical diagnostics, particularly in cancer detection, due to their ability to capture rich spectral information beyond human vision. Traditional approaches for cancer detection rely on handcrafted features and conventional machine learning algorithms, which struggle with high-dimensional spectral data, noise interference, and domain adaptation challenges. Deep learning has recently been introduced to address these limitations, yet existing models often lack robust feature extraction, generalization capability, and effective domain adaptation strategies.
Methods: In this study, we propose a novel deep learning-based time series prediction framework for multispectral and hyperspectral medical imaging analysis. Our approach integrates multi-scale feature extraction, attention mechanisms, and domain adaptation strategies to improve lesion segmentation and disease classification. The model employs self-supervised learning to mitigate the scarcity of labeled medical data, enhancing generalization across different imaging modalities. Furthermore, a knowledge-guided regularization module is introduced to leverage prior medical knowledge, refining predictions and reducing false positives.
Results: Experimental results demonstrate that our framework outperforms state-of-the-art methods in spectral imaging-based cancer detection, achieving superior accuracy, robustness, and interpretability.
Discussion: The proposed approach provides a significant step toward AI-driven medical imaging solutions that effectively harness multispectral and hyperspectral data for enhanced diagnostic performance.

Hyperspectral data have been overshadowed by multispectral data for studying algal blooms for decades. However, newer hyperspectral missions, including the recent Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) Ocean Color Instrument (OCI), are opening the doors to accessible hyperspectral data, at spatial and temporal resolutions comparable to ocean color and multispectral missions. Simulation studies can help to understand the potential of these hyperspectral sensors prior to launch and without extensive field data collection.

Modern reconnaissance technologies, including hyperspectral and multispectral intensity imaging across optical, thermal infrared, terahertz, and microwave bands, can detect the shape, material composition, and temperature of targets. Consequently, developing a camouflage technique that seamlessly integrates both spatial and spectral dimensions across all key atmospheric windows to outsmart advanced surveillance has yet to be effectively developed and remains a significant challenge. In this study, we propose a digital camouflage strategy that covers the optical (0.

Non-invasive diagnostics play a crucial role in medicine, and they ensure both contamination safety and patient comfort. The proposed study integrates hyperspectral imaging with advanced image fusion, enabling non-invasive, diagnostic procedure within tissue. It utilizes near-infrared (NIR) wavelength vision that is suitable for reflections from objects within a dispersive layer, enabling the reconstruction of internal tissue layers images.

With the advancement of precision agriculture, variable-rate spraying (VRS) technology has demonstrated significant potential in enhancing pesticide utilization efficiency and promoting environmental sustainability, particularly in orchard applications. As a critical medium for pesticide transport, the dynamic structural characteristics of orchard canopies exert a profound influence on spraying effectiveness. This review systematically summarizes recent progress in the dynamic perception and modeling of orchard canopies, with a particular focus on key sensing technologies such as LiDAR, Vision Sensor, multispectral/hyperspectral sensors, and point cloud processing techniques.

Introduction: Accurate burn wound assessment is essential for effective treatment, yet it remains heavily dependent on clinical judgment, which is highly subjective. While various optical-based instruments have been developed to address this issue, their clinical effectiveness has been limited due to high cost, penetration depth, lack of portability and validation primarily for use on days 2-5 post injury. The integration of artificial intelligence (AI) with multispectral imaging (MSI) represents a potential advancement in enhancing the accuracy and consistency of wound assessment.
