Problem addressed

Most cameras record video without filter, it causes privacy concern from the public.  Furthermore, those records contain enormous raw data which is hard to use in smart city applications.  ASTRI has developed a customized DNN accelerator to be embedded in smart cameras for smart city applications that contains face detection and object recognition with privay protection by blurring the face.

  • DNN algorithm for privacy protection;
  • Face detection for detecting the person with the privacy protection;
  • Object recognition for detecting the object with auto face blurring for privacy proection.
Key impact
  • Reduced the risk of illegal tracking;  
  • Protected personal image by blurring the face;
  • Reduced workload for object detection;
  • Faster image processing for the privacy protection.
  • Smart camera for smart city
  • Security camera 
  • Smart home camera
