Image reconstruction in optical interferometry: Benchmarking the regularization [PDF]

open access: yes, 2011
With the advent of infrared long-baseline interferometers with more than two telescopes, both the size and the completeness of interferometric data sets have significantly increased, allowing images based on models with no a priori assumptions to be ...

Simulation of 3D Image Reconstruction in Rigid body Motion

open access: yesMATEC Web of Conferences, 2018
3D image reconstruction under rigid body motion is affected by rigid body motion and visual displacement factors, which leads to low quality of 3D image reconstruction and more noise, in order to improve the quality of 3D image reconstruction of rigid ...

3D point cloud generation reconstruction from single image based on image retrieval

open access: yesResults in Optics, 2021
Most of the 3D point cloud generation methods from a single image are only applicable to a single target. However, the real image often contains multiple targets, which is difficult to generate 3D point clouds from the network directly.
