UniSa - IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishThe fusion of multispectral and panchromatic images acquired by sensors mounted on satellite platforms represents a successful application of data fusion called Pansharpening. In this work we propose an algorithm based on morphological pyramid decomposition. This approach implements a Multi Resolution scheme based on morphological gradients for extracting spatial details from the panchromatic image, which are subsequently injected in the multispectral one. Several state-of-the-art methods are considered for comparison. Quantitative and qualitative results confirm the capability of the proposed technique to obtain pansharpened images that outperform state-of-the-art approaches.
