Blur-specific image quality assessment of microscopic hyperspectral images
Quintana, Laura; Ortega, Samuel; Fabelo, Himar; Balea-Fernández, Francisco J.; Callico, Gustavo M. (Peer reviewed; Journal article, 2023)Hyperspectral (HS) imaging (HSI) expands the number of channels captured within the electromagnetic spectrum with respect to regular imaging. Thus, microscopic HSI can improve cancer diagnosis by automatic classification ... -
Characterization of vasskveite (water halibut) syndrome for automated detection
Ortega, Samuel; Ofstad, Ragni; Syed, Shaheen; Kranz, Mathias; Heia, Karsten; Anderssen, Kathryn Elizabeth (Peer reviewed; Journal article, 2023)In recent years, cases of vasskveite (water halibut) syndrome in halibut have been increasing. At the moment, there exists no way to screen for the syndrome immediately after capture, which is problematic for both exporters ... -
