Kindly refer to the following MATLAB Answer where a staff member has answered that the “imgsegkmeans” and “kmeans” functions use similar algorithms under the hood:
The functionality of “imgsegkemeans” is to cluster the images based on the colour of each pixel of that image. As it uses k-means clustering to achieve this, you can refer to the following documentation where the algorithm for k-means clustering has been explained along with the way the distances are computed and used:
I hope this answers your query.
