Journal ArticleDOI
Local-polynomial-approximation-based phase unwrapping using state space analysis
TL;DR: Simulation and experimental results validate the performance of the proposed phase unwrapping method along with its ability of handling the masked phase fringe patterns with the help of a predefined binary mask and a pixel selection strategy.
Journal ArticleDOI
Simultaneous unwrapping and low pass filtering of continuous phase maps based on autoregressive phase model and wrapped Kalman filtering
TL;DR: Simulation and experimental results demonstrate the practical applicability of the proposed phase unwrapping algorithm, which is formulated as state space analysis using the wrapped Kalman filter.
Journal ArticleDOI
Three-dimensional displacement measurement from phase signals embedded in a frame in digital holographic interferometry.
TL;DR: The simulation and experimental results show the robustness of the proposed method to noise and its effectiveness in multiple phase estimation.
Journal ArticleDOI
Automated surface feature detection using fringe projection: An autoregressive modeling-based approach
TL;DR: The simulation and experimental results demonstrate the advantages of the proposed phase based surface evaluation method over the commonly used intensity based methods.
Journal ArticleDOI
Simultaneous estimation of unwrapped phase and phase derivative from a closed fringe pattern
TL;DR: In this article, a new approach for the direct estimation of the unwrapped phase from a single closed fringe pattern is proposed, where the fringe analysis is performed along a given row/column at a time by approximating the phase with a weighted linear combination of linearly independent basis functions.
