Applying the Guassian smoothing formula

Question

How to apply the Guassian smoothing formula for a graph that is in an array?

these arrays are displayed in color and displayed on the chart. I want a linear color gradient after applying Guassian smoothing.

I want to know the exact formula for smoothing the Guassian.

I believe that what you ask for is usually called “Gaussian blur” in photo editing applications. This is simply the result of blurring the image using the Gaussian function, which reduces visual noise and detail. You can learn more about Gaussian blur and Gaussian functions in general information about the excellent Wikipedia articles on subjects, including the nature of formulas and how these functions are usually implemented. The underlying algorithm used is usually the same, but there are several different approaches to its implementation, mainly an attempt to speed up the computation of a computational problem.

If you are looking for code that has already been written to apply Gaussian Blur, check out these links:

• Fast Gaussian Blur v1.3

• Fast Gaussian Blur Algorithm in C #

• C # image processing tutorial 4 - Gaussian Blur

• Fast Gaussian Blur Algorithm in C #

If you are looking for a solution for a drop-down menu that does not require you to do or read any encoding yourself, there are some great openable source frameworks:

• The C # Image Library offers Gaussian blurring among its multiple image processing filters and is incredibly easy to use.

• The AForge.NET Framework provides Gaussian blur as one of many filters in its extensive image processing library.

As for how to apply Gaussian blurring to a graph in an array, you will need to provide more detailed information if you want more specific help (for example, publish code representing the graph objects in question).

For completeness, I'm going to assume that you have a series of Images , each of which is a graph stored in an array. (Although if you just use a standard array, you might consider switching to a strongly typed collection, such as List<Image> .) To apply an effect to your graphs, you can simply iterate over each image in the array and apply the necessary code for a specific implementation, on which you count:

 public void SmoothGraphs(List<Image> graphs) { foreach (Image graph in graphs) { //Apply your Gaussian blur method to the image //(for example, with AForge.NET, you might use the following code:) GaussianBlur filter = new GaussianBlur(4, 11); filter.ApplyInPlace(graph); } }
