High-Order Polynomial Fitting Assistance for Fast Double-Peak Finding in Brillouin-Distributed Sensing [PDF]

open access: yesSensors, 2020
A high-order polynomial fitting method is proposed to accelerate the computation of double-Gaussian fitting in the retrieval of the Brillouin frequency shifts (BFS) in optical fibers showing two local Brillouin peaks.

Polynomial fitting method of background correction for electron backscatter diffraction patterns [PDF]

open access: yesScientific Reports, 2022
A raw electron backscatter diffraction (EBSD) signal can be empirically decomposed into a Kikuchi diffraction pattern and a smooth background. For pattern indexing, the latter is generally undesirable but can reveal topographical, compositional, or ...

Improving the Targets’ Trajectories Estimated by an Automotive RADAR Sensor Using Polynomial Fitting

open access: yesApplied Sciences, 2021
A way to reduce the uncertainty at the output of a Kalman filter embedded into a tracker connected to an automotive RADAR sensor consists of the adaptive selection of parameters during the tracking process. Different informed strategies for automatically

A Polynomial Fitting Problem: The Orthogonal Distances Method

open access: yesMathematics, 2022
The classical curve-fitting problem to relate two variables, x and y, deals with polynomials. Generally, this problem is solved by the least squares method (LS), where the minimization function considers the vertical errors from the data points to the ...

Fast Piecewise Polynomial Fitting of Time-Series Data for Streaming Computing

open access: yesIEEE Access, 2020
Streaming computing attracts intense attention because of the demand for massive data analyzing in real-time. Due to unbounded and continuous input, the volume of streaming data is so high that all the data cannot be permanently stored.

Improved Baseline Correction Method Based on Polynomial Fitting for Raman Spectroscopy

open access: yesPhotonic Sensors, 2018
Raman spectrum, as a kind of scattering spectrum, has been widely used in many fields because it can characterize the special properties of materials. However, Raman signal is so weak that the noise distorts the real signals seriously. Polynomial fitting
