Depth and All-in-Focus Image Estimation in Synthetic Aperture Integral Imaging Under Partial Occlusions [PDF]

open access: yesIEEE Access, 2019
A common assumption in the integral imaging reconstruction is that a pixel will be photo-consistent if all viewpoints observed by the different cameras converge at a single point when focusing at the proper depth.

3-D computational synthetic aperture integral imaging (COMPSAII)

open access: yesOptics Express, 2003
We propose a computational synthetic aperture integral imaging technique that increases the field of view (FOV) and viewing angle of integral imagines systems. The synthetic aperture is obtained by relative movement of the imaging system and the object in a plane perpendicular to the optical axis.

3D Image Display Method using Synthetic Aperture integral imaging [PDF]

open access: yesThe Journal of the Korean Institute of Information and Communication Engineering, 2012
Synthetic aperture integral imaging is one of promising 3D imaging techniques to capture the high-resolution elemental images using multiple cameras. In this paper, we propose a method of displaying 3D images in space using the synthetic aperture integral imaging technique.

Three-Dimensional Visualization Using Proportional Photon Estimation Under Photon-Starved Conditions [PDF]

open access: yesSensors
In this paper, we propose a new method for three-dimensional (3D) visualization that proportionally estimates the number of photons in the background and the object under photon-starved conditions.

Designing optical 3D images encryption and reconstruction using monospectral synthetic aperture integral imaging

open access: yesOptics Express, 2018
This paper realizes an optical 3D images encryption and reconstruction by employing the geometric calibration algorithm to the monospectral synthetic aperture integral imaging system. This method has the simultaneous advantages of improving the quality of 3D images by eliminating the crosstalk from the unaligned cameras and increasing security of the ...

Inverse Airborne Optical Sectioning

open access: yesDrones, 2022
We present Inverse Airborne Optical Sectioning (IAOS), an optical analogy to Inverse Synthetic Aperture Radar (ISAR). Moving targets, such as walking people, that are heavily occluded by vegetation can be made visible and tracked with a stationary ...

Diffraction From Metallic Objects in Radar Imaging—Theory, Simulation, and Experimental Verification

open access: yesIEEE Journal of Microwaves, 2022
The paper describes the modelling of diffraction effects in radar imaging scans at and near sharp-edged metallic objects as the aperture dimension is close to the dimension of the object to be scanned.

Even sampling photonic-integrated interferometric array for synthetic aperture imaging

open access: yesOptics Express, 2022
To improve the effectiveness of spatial spectrum sampling for the photonic-integrated interferometric imaging, an array forming scheme is proposed with evenly distributed interferometric baselines, which is referred to as the even sampling photonic-integrated interferometric array (ESPIA).

Three-Dimensional Integral Imaging with Enhanced Lateral and Longitudinal Resolutions Using Multiple Pickup Positions

open access: yesSensors, 2022
In this paper, we propose an enhancement of three-dimensional (3D) image visualization techniques by using different pickup plane reconstructions. In conventional 3D visualization techniques, synthetic aperture integral imaging (SAII) and volumetric ...
