📰 Medium · Data Science

Learn image segmentation using K-Means, Gaussian Mixture Models, and Mean Shift algorithms to understand how clustering algorithms see pictures

intermediate Published 11 Jul 2026

Action Steps

Apply K-Means clustering to an image by converting it into a cloud of points
Use Gaussian Mixture Models to segment an image by fitting a probabilistic model to the data
Implement Mean Shift algorithm to segment an image without specifying the number of clusters
Compare the results of different clustering algorithms on the same image
Evaluate the performance of each algorithm using metrics such as accuracy and precision

Who Needs to Know This

Data scientists and machine learning engineers can benefit from this article to improve their image segmentation skills and apply clustering algorithms to real-world problems
