Robust automated reading of the skin prick test via 3D imaging and parametric surface fitting

Pineda J.; Vargas R.; Romero L.A.; Marrugo J.; Meneses J.; Marrugo A.G. (Public Library of Science, 2019)

The conventional reading of the skin prick test (SPT) for diagnosing allergies is prone to inter- and intra-observer variations. Drawing the contours of the skin wheals from the SPT and scanning them for computer processing ...

Evaluating the influence of camera and projector lens distortion in 3D reconstruction quality for fringe projection profilometry

Vargas R.; Marrugo A.G.; Pineda J.; Meneses J.; Romero L.A. (OSA - The Optical Society, 2018)

We study the influence of geometric distortions of the camera and projector lenses on 3D reconstruction quality for fringe projection profilometry. Experimental results on real objects and their 3D models show the accuracy ...

Wide-field 3D imaging with an LED pattern projector for accurate skin feature measurements via Fourier transform profilometry

Marrugo A.G.; Romero L.A.; Meneses J. (SPIE, 2019)

Accurate 3D imaging of human skin features with structured light methods is hindered by subsurface scattering, the presence of hairs and patient movement. In this work, we propose a wide-field 3D imaging system capable of ...

Toward an automatic 3D measurement of skin wheals from skin prick tests

Marrugo A.G.; Romero L.A.; Pineda J.; Vargas R.; Altamar Mercado, Hernando; Marrugo J.; Meneses J. (SPIE, 2019)

The skin prick test (SPT) is the standard method for the diagnosis of allergies. It consists in placing an array of allergen drops on the skin of a patient, typically the volar forearm, and pricking them with a lancet to ...

A structure-from-motion pipeline for topographic reconstructions using unmanned aerial vehicles and open source software

Meza J.; Marrugo A.G.; Sierra E.; Guerrero M.; Meneses J.; Romero L.A. (Springer Verlag, 2018)

In recent years, the generation of accurate topographic reconstructions has found applications ranging from geomorphic sciences to remote sensing and urban planning, among others. The production of high resolution, ...
