One way to do it is to use a Savitzky-Golay filter, basically a moving/sliding polynomial fit. See the attached code, below the screenshot, for a demo. clc; % Clear the command window.
close all; % Close all figures (except those of imtool.)
clear; % Erase all existing variables. Or clearvars if you want.
workspace; % Make sure the workspace panel is showing.
format long g;
format compact;
fontSize = 25;
% Make a noisy sine wave signal
x = 1 : 300;
period = 50
y = sin(2*pi*x/period);
noiseAmplitude = 0.8;
y = y + noiseAmplitude * rand(size(y))
