Detection and removal of dust artifacts in retinal images via sparse-based inpainting
(2021-09-06)
Dust particle artifacts are present in all imaging modalities but have more adverse consequences in
medical images like retinal images. They could be mistaken as small lesions, such as microaneurysms.
We propose a method ...
Desarrollo e implementación de un perfilómetro óptico por triangulación láser
(2020-12-24)
Profilometers are instruments commonly used in surface metrology tasks. These instruments play a key role in the industry, such as in manufacturing and quality assurance. However, conventional profilometry techniques require ...
Trade-Off Asymmetric Profile for Extended-Depth-of-Focus Ocular Lens
(2022-02-19)
We explore the possibility of extending the depth of focus of an imaging lens with an
asymmetric quartic phase-mask, while keeping the aberration within a relatively low level. This can be intended, for instance, for ...
Development and implementation of an optical profilometer by laser triangulation
(2020)
Profilometers are instruments commonly used in surface metrology tasks. These instruments play a key role in the industry, such as in manufacturing and quality assurance. However, conventional profilometry techniques require ...
Generative Adversarial Networks for Cell Segmentation in Human Corneal Endothelium
(2022)
We generate synthetic images with a generative adversarial network (GAN) model trained with image patches from specular microscopy corneal endothelial cells. Preliminary results show it may be a suitable approach for ...
MarkerPose: Robust real-time planar target tracking for accurate stereo pose estimation
(2021)
Despite the attention marker-less pose estimation has attracted in recent years, marker-based approaches still provide unbeatable accuracy under controlled environmental conditions. Thus, they are used in many fields such ...
Corneal endothelium assessment in specular microscopy images with Fuchs’ dystrophy via deep regression of signed distance maps
(2023)
Specular microscopy assessment of the human corneal endothelium (CE) in Fuchs’ dystrophy is challenging due to the presence of dark image regions called guttae. This paper proposes a UNet-based segmentation approach that ...
Modeling a Structured Light System with Open-Source Software
(2022)
We propose modeling a structured light system with open-source computer graphics software to perform experimental verifications independently of the physical system. Encouraging experimental results show the capabilities ...
