  • Galdran, Adrian; Carneiro, Gustavo; González Ballester, Miguel Ángel, 1973- (Springer, 2021)
    A large number of different lesions and pathologies can affect the human digestive system, resulting in life-threatening situations. Early detection plays a relevant role in the successful treatment and the increase of ...
  • Galdran, Adrian; Carneiro, Gustavo; González Ballester, Miguel Ángel, 1973- (Springer, 2021)
    Highly imbalanced datasets are ubiquitous in medical image classification problems. In such problems, it is often the case that rare classes associated to less prevalent diseases are severely under-represented in labeled ...
  • Galdran, Adrian; Carneiro, Gustavo; González Ballester, Miguel Ángel, 1973- (Springer, 2021)
    Polyps represent an early sign of the development of Colorectal Cancer. The standard procedure for their detection consists of colonoscopic examination of the gastrointestinal tract. However, the wide range of polyp shapes ...
  • Galdran, Adrian; Vazquez-Corral, Javier; Pardo, David; Bertalmío, Marcelo (Institute of Electrical and Electronics Engineers (IEEE), 2017)
    We propose a novel image-dehazing technique based on the minimization of two energy functionals and a fusion scheme to combine the output of both optimizations. The proposed fusion-based variational image-dehazing (FVID) ...
  • Vazquez-Corral, Javier; Zamir, Syed Waqas; Galdran, Adrian; Pardo, David; Bertalmío, Marcelo (The Society for Imaging Science and Technology (IS&T), 2016)
    The retinex theory of color vision has been a light of inspiration for color researchers since its inception 50 years ago. It has been adapted to work for different goals such as shadow removal, high dynamic range imaging, ...
  • Galdran, Adrian; Bria, Alessandro; Álvarez-Gila, Aitor; Vazquez-Corral, Javier; Bertalmío, Marcelo (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    Image dehazing deals with the removal of undesired lossof visibility in outdoor images due to the presence of fog.Retinex is a color vision model mimicking the ability ofthe Human Visual System to robustly discount varying ...
  • Galdran, Adrian; Hewitt, Katherine J.; Ghaffari Laleh, Narmin; Kather, Jakob N.; Carneiro, Gustavo; González Ballester, Miguel Ángel, 1973- (Springer, 2022)
    Tissue typology annotation in Whole Slide histological images is a complex and tedious, yet necessary task for the development of computational pathology models. We propose to address this problem by applying Open Set ...
  • Galdran, Adrian; Vazquez-Corral, Javier; Pardo, David; Bertalmío, Marcelo (Springer, 2015)
    Images captured under adverse weather conditions, such as haze or fog, typically exhibit low contrast and faded colors, which may severely limit the visibility within the scene. Unveiling the image struc- ture under the ...
