The multi-rotor aircraft for detected the number of crowd, and to prevent the Terrorists

The development of multi-rotor UAVs for the security and protection purposes, the UAV is using the Imageprocessing technology Image processing and the using the machine learning through the algorithms named Convolutional Neural Networks (CNN). The algorithm is to create an artificial intelligence (AI) which focuses a bird-eye view of the humanoid movement, which could follow such a target object (Moving object tracking). The UAV could be real-time both video r and photos recorded. The information will be automatically saved and sent back to the mobile application (mobile app) for a convenient coordination with the relevant governmental agencies.
