how the subtractive clustering can be applied on a gray scale image?

can you send me the codes to apply subtractive clustering on gray scale image,or how we decide the cluster center using subtractive clustering.After finding cluster center how we assign these centers in k-means clustering.

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!
