There are two steps required :
1) Converting data from CSV file to matrix format
2) Reading that matrix and applying Laplacian of Gaussian filter
1. Converting data from CSV file to matrix format
A = readmatrix(filename);
This will load data from CSV file to a matrix. For more information refer to below link: https://www.mathworks.com/help/matlab/ref/readmatrix.html
2.Reading that matrix and applying Laplacian of Gaussian filter
- Use "fspecial" function to create Laplacian of Gaussian filter. Pass value of input argument “type” as “log” for creating Laplacian of Gaussian filter. For example:
Log_filter = fspecial('log', [5,5], 4.0);
For more information please refer to the below link:
- Use "imfilter" to perform the filtering operation on the input matrix. For more information refer to below link:https://www.mathworks.com/help/images/ref/imfilter.html
There is a similar code for performing Laplacian of Gaussian filtering in below link:
