      Alterini, Tommaso; Díaz Douton, Fernando; Vilaseca Ricart, Meritxell (International Society for Photo-Optical Instrumentation Engineers (SPIE), 2019)
      Conference report
      Restricted access - publisher's policy
      Eye fundus photography routinely used in clinical practice is restricted to color imaging of the retina. In the last years, hyperspectral imaging has shown to be a powerful tool for the spectral analysis of biological ...

    • Hyperspectral imaging for skin cancer and blood disorders diagnosis 

      Vilaseca Ricart, Meritxell; Burgos Fernández, Francisco Javier; Rey Barroso, Laura; Roldán, Mónica; Gassiot Riu, Susanna; Sarrate Garcia, Edurne; Isola, Ignacio; Ruiz Llobet, Anna (2022-10-07)
      Article
      Open Access
      Hyperspectral imaging is a novel technology for acquiring an image at a large number of wavelengths, thus allowing the study of spectral and spatial details of a sample under analysis. This technology has emerged as a ...
