Análisis colorimétrico de estructuras de fondo de ojo mediante retinografía multiespectral
(2022)
Conference report
Open AccessEl análisis del fondo del ojo es crucial para prevenir enfermedades retinianas y coroideas ya que la mayoría no causan síntomas en etapas tempranas. Tratarlas cuando aparecen los primeros indicios es fundamental para evitar ... -

Artificial intelligence to identify retinal fundus images, quality validation, laterality evaluation, macular degeneration, and suspected glaucoma
(2020-02-13)
Article
Open AccessPurpose: To assess the performance of deep learning algorithms for different tasks in retinal fundus images: (1) detection of retinal fundus images versus optical coherence tomography (OCT) or other images, (2) evaluation ... -
Colorimetric analysis of eye fundus structures with multispectral retinography
(International Colour Association (AIC), 2021)
Conference lecture
Open AccessThe analysis of the eye fundus is critical to prevent retinal and choroidal diseases since most of them cause no symptoms at early stages. Treating them when the very first signs appear is crucial to avoid vision losses. ... -
Connectivity-based segmentation of retinal vessels in eye fundus images
(2017-12)
Article
Open Access© Sociedad Española de Óptica. A new unsupervised method for segmentation of objects of diverse nature with the common feature of connectivity (e.g. branching trees or net-shaped objects) is proposed. A preferred application ... -
Data augmentation for deep learning of non-mydriatic screening retinal fundus images
(Springer, 2018)
Conference report
Restricted access - publisher's policyFundus image is an effective and low-cost tool to screen for common retinal diseases. At the same time, Deep Learning (DL) algorithms have been shown capable of achieving similar or even better performance accuracies than ... -

Fast visible and extended nearinfrared multispectral fundus camera
(2019-09)
Article
Open AccessWe present a multispectral fundus camera that performs fast imaging of the ocular posterior pole in the visible and near-infrared (400 to 1300 nm) wavelengths through 15 spectral bands, using a flashlight source made of ... -
Hyperspectral eye fundus imaging with extended spectral range towards the near infrared
(International Society for Photo-Optical Instrumentation Engineers (SPIE), 2019)
Conference report
Restricted access - publisher's policyEye 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 ... -

Conference lecture
Open AccessSpectral reflectance of the eye fundus was evaluated in adult healthy patients through a fast visible and near-infrared multispectral fundus camera. Spectral signatures were analyzed for different ocular structures of the ... -
Network-based features for retinal fundus vessel structure analysis
(Public Library of Science (PLOS), 2019-01-01)
Article
Open AccessRetinal fundus imaging is a non-invasive method that allows visualizing the structure of the blood vessels in the retina whose features may indicate the presence of diseases such as diabetic retinopathy (DR) and glaucoma. ... -

Reflectance evaluation of eye fundus structures with a visible and near-infrared multispectral camera
(2022-06-01)
Article
Open AccessWe 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 ... -
Retinal vessel local tortuosity under a macula-to-optic disc central-framing change
(2023-03-01)
Article
Open AccessSome ocular and cardiovascular diseases can be detected through the increased tortuosity of retinal blood vessels. Objective tortuosity measures can be obtained from digital image analysis of a retinography. This study ... -
