We can develop a 
feature for detecting faces that can precisely overlay interactive masks and filters on the user's face, similar to the functionalities seen on Instagram or Snapchat. Furthermore, it offers intelligent software solutions with AI-powered image and video processing tools, including beautification retouch presets. 
Similarly, for security systems, we can integrate facial recognition to identify individuals by accessing a database of known faces. Both of these features can assist in crowd management. We can add AI algorithms that analyze crowd density and movement to ensure public safety in crowded areas or events, utilizing computer vision applications.
