On the Nonlinear Shaping Gain With Probabilistic Shaping and Carrier Phase Recovery

open access: yesJournal of Lightwave Technology, 2023
The performance of different probabilistic amplitude shaping (PAS) techniques in the nonlinear regime is investigated, highlighting its dependence on the PAS block length and the interaction with carrier phase recovery (CPR). Different PAS implementations are considered, based on different distribution matching (DM) techniques-namely, sphere shaping ...

Integrating qualitative and quantitative shape recovery [PDF]

open access: yesInternational Journal of Computer Vision, 1994
Recent work in qualitative shape recovery and object recognition has focused on solving the what is it" problem, while avoiding the where is it" problem. In contrast, typical CAD-based recognition systems have focused on the where is it" problem, while assuming they know what the object is.

Better Shading for Better Shape Recovery [PDF]

open access: yes2014 IEEE Conference on Computer Vision and Pattern Recognition, 2014
The basic idea of shape from shading is to infer the shape of a surface from its shading information in a single image. Since this problem is ill-posed, a number of simplifying assumptions have been often used. However they rarely hold in practice. This paper presents a simple shading-correction algorithm that transforms the image to a new image that ...

A Linearization–Based Hybrid Approach for 3D Reconstruction of Objects in a Single Image

open access: yesInternational Journal of Applied Mathematics and Computer Science, 2021
The shape-from-shading (SFS) technique uses the pattern of shading in images in order to obtain 3D view information. By virtue of their ease of implementation, linearization-based SFS algorithms are frequently used in the literature.
