Automated corneal endothelium image segmentation in the presence of cornea guttata via convolutional neural networks
Sierra, Juan S.; Pineda, Jesus; Viteri, Eduardo; Rueda, Daniela; Tibaduiza, Beatriz; Berrospi, Rúben D.; Tello, Alejandro; Galvis, Virgilio; Volpe, Giovanni; Millán, María S.; Romero, Lenny A.; Marrugo Hernández, Andrés Guillermo (Cartagena de Indias, 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 ... -
Corneal endothelium assessment in specular microscopy images with Fuchs’ dystrophy via deep regression of signed distance maps
Sierra, Juan S.; Pineda, Jesus; Rueda, Daniela; Tello, Alejandro; Prada, Angélica M.; Galvis, Virgilio; Volpe, Giovanni; Millan, Maria S.; Romero, Lenny A.; Marrugo, Andres G. (Cartagena de Indias, 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 ... -
Skin color correction via convolutional neural networks in 3D fringe projection profilometry
Barrios, Erik; Pineda, Jesus; Romero, Lenny A; Millán, María S; Marrugo, Andrés G. (Cartagena de Indias, 2021-09-02)Fringe Projection Profilometry (FPP) with Digital Light Projector technology is one of the most reliable 3D sensing techniques for biomedical applications. However, besides the fringe pattern images,often a color texture ... -
Toward the generation of reproducible synthetic surface data in optical metrology
Pineda, Jesus; Altamar Mercado, Hernando; Romero, Lenny A.; Marrugo Hernández, Andrés Guillermo (Cartagena de Indias, 2020-05-19)The implementation and generation of synthetic data for testing algorithms in optical metrology are often difficult to reproduce. In this work, we propose a framework for the generation of reproducible synthetic surface ...
