Filtering and Smoothing Data - MATLAB & Simulink

Description. W = smooth3 (V) smooths the input data V and returns the smoothed data in W. W = smooth3 (V,'filter') filter determines the convolution kernel and can be one of these values: 'gaussian'. 'box' (default) W = smooth3 (V,'filter',size) sets the size of the convolution kernel (default is [3 3 3] ) Smoothing is a method of reducing the noise within a data set. Curve Fitting Toolbox™ allows you to smooth data using methods such as moving average, Savitzky-Golay filter and Lowess models or by fitting a smoothing spline. Smooth data interactively using the Curve Fitting app or at the command line using the smooth function How to smooth data in matlab without using method from any toolkit. I am trying to smooth some measurement data in Matlab and I think so, I am missing something. I wrote my own code to create the Gaussian window. However rest of code is copied from this link: % Generate sample data. vector = 5* (1+cosd (1:3:180)) + 2 * rand (1, 60); hist (vector) smoothts smooths the input data using the specified method. output = smoothts (input) smooths the input data using the default Box method with window size, wsize, of 5. output = smoothts (input,'b',wsize) smooths the input data using the Box (simple, linear) method. wsize specifies the width of the box to be used

The Smooth Data task lets you interactively smooth noisy data. The task automatically generates MATLAB ® code for your live script. Using this task, you can: Customize the method for smoothing data in a workspace variable Many data processing functions in MATLAB®, including smoothdata, movmean, and filloutliers, allow you to provide sample points, ensuring that data is processed relative to its sampling units and frequencies. To remove the high-frequency variation in the first half hour of data in Airreg, use the 'SamplePoints' option with the time stamps in time 此 MATLAB 函数 使用以启发方式确定的固定窗口长度返回向量元素的移动平均值。窗口向下滑动向量的长度,计算每个窗口中的元素的平均值。 如果 A 为矩阵,smoothdata 计算每列的移动平均值。 如果 A 是多维数组,则 smoothdata 沿大小不等于 1 的第一个维度进行运算

  3. In statistics and image processing, to smooth a data set is to create an approximating function that attempts to capture important patterns in the data, while leaving out noise or other fine-scale structures/rapid phenomena. In smoothing, the data points of a signal are modified so individual points higher than the adjacent points (presumably because of noise) are reduced, and points that are.

The functions evaluate the cubic spline interpolating the data specified in the vectors x and y at all of the points in the vector u

Interpolating with cubic splines using Matlab If you have a lot of data points then there is a way to interpolate the data with a low degree polynomial. To do this you only interpolate four points at once using a special cubic polynomial function called a cubic spline function. Imagine that you have 10 data points. The cubic spline function interpolates the first four data points (1-4) with a. MATLAB also has powerful built-in routines for drawing contour and three-dimensional surface plots z = f(x,y) data. MATLAB plotting commands are best illustrated by example. I have tried to make the examples compact, while avoiding the trivial. The examples build on each other so it is advisable to at least skim through the presenation in order. Jumping from link to link will probably be more.

In this project we propose a framework to increase the embedding capacity of reversible data hiding techniques that use a difference of image to embed data. The main idea is that, instead of taking the difference of the neighboring pixels, we rearrange the columns (or rows) of the image in a way that enhances the smooth regions of an image. Any difference based technique to embed data can then.
