Retinal image analysis: Image processing and feature extraction oriented to the clinical task
(Sociedad Espanola de Optica, 2017)
Medical digital imaging has become a key element of modern health care procedures. It provides visual documentation and a permanent record for the patients, and most important the ability to extract quantitative information ...
Multi-target Attachment for Surgical Instrument Tracking
(2021-06-16)
The pose estimation of a surgical instrument is a common problem in the new needs of medical science. Many instrument tracking methods use markers with a known geometry that allows for solving the
instrument pose as ...
Skin prick test wheal detection in 3D images via convolutional neural networks
(2021-10-01)
The skin prick test (SPT) is performed to diagnose different types of allergies. This medical procedure requires measuring the size of the skin wheals that
appear when the test is performed. However, the manual measurement ...
Quality changes in fundus images of pseudophakic eyes
(Sociedad Espanola de Optica, 2018)
We consider the changes produced in the quality of eye fundus images of patients before and after cataract surgery with intraocular lens implantation and propose a measure to quantitatively assess those changes. Several ...
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 ...
What is the best triangulation approach for a structured light system?
(2020-05-18)
It has become customary to calibrate a camera-projector pair in a structured light (SL) system as a stereo-vision setup. The 3D reconstruction is carried out by triangulation from the detected point at the camera sensor ...
SPUD: Simultaneous phase unwrapping and denoising algorithm for phase imaging
(2020-05-01)
Recent methods for phase unwrapping in the presence of noise include denoising algorithms to filter out noise as a preprocessing stage. However, including a denoising stage increases the overall computational complexity ...

Active and reactive power conditioning using SMES devices with PMW-CSC: A feedback nonlinear control approach
(Ain Shams University, 2019)
The active and reactive power conditioning using superconducting magnetic energy storage (SMES) systems for low-voltage distribution networks via feedback nonlinear control is proposed in this paper. The SMES system is ...
On the nonlinear control of a single-phase current source converter for sinusoidal voltage generation
(2020)
Colombian power system is being transformed for the large-scale integration of renewable energy resources and energy storage systems; all of these are integrated by power electronic converters controlled by voltage and ...
