On the compensation of uneven illumination in retinal images for restoration by means of blind deconvolution
(Institute of Electrical and Electronics Engineers Inc., 2016)
Retinal eye fundus images are used for diagnostic purposes, but despite controlled conditions in acquisition they often suffer from uneven illumination and blur. In this work, we propose the use of multi-channel blind ...
Acquisition and Analysis of Cognitive Evoked Potentials using an Emotiv Headset for ADHD Evaluation in Children
(Institute of Electrical and Electronics Engineers Inc., 2019)
Attention-deficit/hyperactivity disorder (ADHD) is a neurological condition that affects the quality of life of the patients. It can be diagnosed using a combination of psychological tests. In addition to that, the brain ...
HoloEasy, a web application for computer generated holograms
(Springer Verlag, 2018)
If the appropriate phase and/or amplitude profile is placed on a Diffractive Optical Element (DOE) it can practically generate an image of an object (hologram) by diffraction of the light. The problem of generating computer ...
Speckle free optical watermarking based on pseudo-random phase encoding
(Institute of Electrical and Electronics Engineers Inc., 2016)
Watermarking is a process of embedding copiright information into an image to verify the ownership without any kind of corruption. In optical applications, the usage of diffusers is required to obtain a homogeneously ...
A low noise stenography method for medical images with QR encoding of patient information
(SPIE, 2017)
This paper proposes an approach to facilitate the process of individualization of patients from their medical images, without compromising the inherent confidentiality of medical data. The identification of a patient from ...
Automated corneal endothelium image segmentation in the presence of cornea guttata via convolutional neural networks
(2020-08)
Automated cell counting in in-vivo specular microscopy images is challenging, especially in situations where single-cell segmentation methods fail due to pathological conditions. This work aims to obtain reliable cell ...
