Autofluorescence Image Reconstruction and Virtual Staining for In-Vivo Optical Biopsying
Picón Ruiz, Artzai ; Medela Ayarzaguena, Alfonso; Sánchez Peralta, Luisa F.; Cicchi, Riccardo; Bilbao, Roberto; Alfieri, Domenico; Elola Artano, Andoni; Glover, Ben; López Saratxaga, Cristina (IEEE-Institute of Electrical and Electronics Engineers, 2021-02-22)Modern photonic technologies are emerging, allowing the acquisition of in-vivo endoscopic tissue imaging at a microscopic scale, with characteristics comparable to traditional histological slides, and with a label-free ... -
Biologically-inspired data decorrelation for hyper-spectral imaging
Picón Ruiz, Artzai ; Ghita, Ovidiu; Rodríguez Vaamonde, Sergio; Iriondo Bengoa, Pedro María ; Whelan, Paul F. (Springer, 2011)Hyper-spectral data allows the construction of more robust statistical models to sample the material properties than the standard tri-chromatic color representation. However, because of the large dimensionality and complexity ... -
Constellation Loss: Improving the Efficiency of Deep Metric Learning Loss Functions for the Optimal Embedding of Histopathological Images
Background: Deep learning diagnostic algorithms are proving comparable results with human experts in a wide variety of tasks, and they still require a huge amount of well-annotated data for training, which is often non ... -
