Wooptix is always working and researching, deepening more and more in the novelties of the technological sector and of each one of our technologies and solutions, it is a sector in constant movement in which new products appear every day. We frequently publish papers in various digital and physical media.
Monocular Real Time Full Resolution Depth Estimation Arrangement with a Tunable Lens / March 2022

Monocular Real Time Full Resolution Depth Estimation Arrangement with a Tunable Lens / March 2022

Ricardo Oliva-García, Sabato Ceruso, José G. Marichal-Hernández and José M. Rodriguez-Ramos

This work introduces a real-time full-resolution depth estimation device, which allows integral displays to be fed with a real-time light-field. The core principle of the technique is a high-speed focal stack acquisition method combined with an efficient implementation of the depth estimation algorithm, …

The optics of the human eye at 8.6 µm resolution / December 2021

The optics of the human eye at 8.6 µm resolution / December 2021

Wooptix’ team with the collaboration of Damien Gatinel & Jack T. Holladay

In this work, we characterize the in vivo ocular optics of the human eye with a lateral resolution of 8.6 microns, which implies roughly 1 million measurement points for a pupil diameter of 9 mm. The results suggest that the normal human eye presents a series of hitherto unknown optical patterns. This discovery could have a great impact on the way we understand some fundamental mechanisms of human vision.

Relative multiscale deep depth from focus / August 2021

Relative multiscale deep depth from focus / August 2021

Sabato Ceruso, Sergio Bonaque-González, Ricardo Oliva-García, José Manuel Rodríguez-Ramos

The problem of reconstructing a depth map from a sequence of differently focused images (focal stack) is called Depth from focus. The core idea of this method is to analyze the sharpness of each pixel and compare it along the axis of the focal stack to estimate the true depth value. This approach has two main drawbacks: it depends on the optics of the camera and on the focus measure operator…

Inverse Multiscale Discrete Radon Transform by Filtered Backprojection / July 2021

Inverse Multiscale Discrete Radon Transform by Filtered Backprojection / July 2021

José G. Marichal-Hernández, Ricardo Oliva-García, Óscar Gómez-Cárdenes, Iván Rodríguez-Méndez, José M. Rodríguez-Ramos

The Radon transform is a valuable tool in inverse problems such as the ones present in electromagnetic imaging. Up to now the inversion of the multiscale discrete Radon transform has been only possible by iterative numerical methods while the continuous Radon transform is usually tackled…
