Hello to you all
I have an image that contains points and I want to combine these points based on the distance between them and finally surround each group;
Thank you for your help, and here attached an example of the image

Hi Maa Kari,
You can shrink the spots to a single point using bwmorph().
Then you may classify them according to their X and Y position, or you can use a perceptron for classification.
Good luck ;)

It sounds like you don't have an image but actually just a list of x,y coordinates. Do you have the Statistics and Machine Learning Toolbox? There are functions in there for clustering/classification. For example, you could use kmeans().

The Statistics and Machine Learning Toolbox provides supervised and unsupervised machine learning algorithms, including support vector machines (SVMs), boosted and bagged decision trees, k-nearest neighbor, k-means, k-medoids, hierarchical clustering, Gaussian mixture models, and hidden Markov models.
