Reflectance evaluation of eye fundus structures with a visible and near-infrared multispectral camera
(2022-06-01)
Article
Accés obertWe examined the spectral reflectance of fundus structures in the visible and near-infrared (400–1300 nm) range for contributing to the medical diagnosis of fundus diseases. Spectral images of healthy eye fundus and other ... -
