This extension is designed to detect and block images of Vladimir Putin on the web using facial recognition machine learning algorithms. However, it is important to note that this is an experimental extension and running machine learning algorithms can be quite resource-intensive. The detection speed can vary depending on your hardware (a better GPU certainly helps). All images smaller than 100px are ignored.
