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

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 ...
