Compressed Sensing Shape Estimation of Star-Shaped Objects in Fourier Imaging

IEEE Signal Processing Letters, 2007
Recent theory of compressed sensing informs us that near-exact recovery of an unknown sparse signal is possible from a very limited number of Fourier samples by solving a convex L1 optimization problem. The main contribution of the present letter is a compressed sensing-based novel nonparametric shape estimation framework and a computational algorithm ...

Shape Sensing Using Multi-core Fiber

Optical Fiber Communication Conference, 2015
A method of converting multi-core fiber strain and twist measurements into three dimensional shape measurements using Frenet-Serret equations adapted to the treatment of a multi-core optical fiber as a Kirchhoff elastic rod is presented.

Analysis of shape sensing accuracy employing distributed fiber sensing

Optical Sensors 2025
This work presents an analysis of the impact of noise spatial distribution shape reconstruction accuracy employing Monte-Carlo simulations. The findings reveal how noise introduced at the initial segments of the curve negatively affects the reconstructed shape accuracy more than an equivalent amount of noise applied towards the curve end, providing a ...
