A particle swarm optimization approach to log-gabor filtering in fourier transform profilometry

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

In this work, we propose a particle Swarm Optimization approach to Log-Gabor filtering in Fourier transform profilometry. Encouraging experimental results show the advantage of the proposed method. © 2018 The Author(s)

Background intensity removal in structured light three-dimensional reconstruction

Vargas R.; Pineda J.; Marrugo A.G.; Romero L.A. (Institute of Electrical and Electronics Engineers Inc., 2016)

In Fourier Transform Profilometry, a filtering procedure is performed to separate the desired information (first order spectrum) from other unwanted contributions such as the background component (zero-order spectrum). ...

Background intensity removal in Fourier transform profilometry: A comparative study

Vargas R.; Pineda J.; Romero L.A.; Marrugo A.G. (OSA - The Optical Society, 2016)

We study the removal of the background intensity of fringe patterns via Empirical Mode Decomposition and the Hilbert Transform. Simulation results show that the latter provides a suitable background compensation with minimal ...

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 ...
