Thanks a lot for all your ideas, I really appreciate them. I finally used curve fitting in MATLAB using pchip interpolation in 1D and then extending the case in 2D by using the fittedmodel from cftool. Smoothing splines didn’t work in my case as it results in an overshoot

A 2D Savitzky Golay filter is similar, and I already have code for that. Basically it replaces each pixel with a polynomial fit over a sliding window. It gives the effect of smoothing. Let me know if you have the Signal Processing Toolbox and would like my demo.

The following Matlab project contains the source code and Matlab examples used for smoothing 2d contours using local regression lines. A contour of a 2D region is defined by an ordered set of points where the neighboring elements contain the neighboring points.

There is a smooth function in matlab which will probably give you all the functionality you need. Without knowing anything about your data (in terms of how much smoothing you need etc.) I cant give too many specifics but if you type in doc smooth at your matlab

Yes you need two matrices. The first matrix is the data (i.e., your 100×100 matrix A) the second is your Gaussian filter h. You can make this filter with: Select a Web Site Choose a web site to get translated content where available and see local events and offers.

Using the Curve Fitting app or the fit function, you can fit cubic spline interpolants, smoothing splines, and thin-plate splines. Other Curve Fitting Toolbox functions allow more specialized control over spline construction. For example

This MATLAB function filters the grayscale image I using a pixel-wise adaptive low-pass Wiener filter. J = wiener2(I,[m n],noise) filters the grayscale image I using a pixel-wise adaptive low-pass Wiener filter. [m n] specifies the size (m-by-n) of the neighborhood used

9/8/2013 · CellSegm, the software presented in this work, is a Matlab based command line software toolbox providing an automated whole cell segmentation of images showing surface stained cells, acquired by fluorescence microscopy. It has options for both fully

Smooth a 2D polyline through interpolation (Catmull-Rom) or approximation (Chaikin) Thank you. Yep the Chaikin method was new to me too. And it is very pragmatic, which I like. Thanks for you new article also. I will read more intently soon on the NURBS.

Get started with surface fitting, interactively using Curve Fitting app or programmatically using the fit function. In the Curve Fitting app, select X Data, Y Data and Z Data.Curve Fitting app creates a default interpolation fit to the data. Choose a different model type using

How to plot a Gaussian distribution or bell curve in Matlab In statistics and probability theory, the Gaussian distribution is a continuous distribution that gives a good description of data that cluster around a mean. The graph or plot of the associated probability density
