Hey Pooja,
- In order to perform subtractive clustering, you can use the "subclust" function. This function accepts matrices of size MxN as well. You can use the grayscale image as an input in the form of a matrix by referring the following documentation: https://www.mathworks.com/help/fuzzy/subclust.html
- For using the obtained cluster centres, specify the initial cluster centers using the "Start" parameter while performing the kmeans clustering. For more information refer to the "Name-Value Arguments" section in the following documentation: https://www.mathworks.com/help/stats/kmeans.html#namevaluepairarguments:~:text=double%20%7C%20single-,Start,-%E2%80%94%20Method%20for
I hope this helps!
