SmartCity is a project ,using an intelligent camera ,that allows security teams, like army or paramedics, to have detailed list of ,how many people are in a given place , how old are them, what is their gender, all this in real time: In a case of earth strike or missiles these data are very important to save lives:

An OpenCV model which can predict a person's probable Age and Gender in real time as well as from stored images.

A deep learning model to detect the age of a person

This AI age detection project is being developed for the Spring 2024, CSC481: Artificial Intelligence, class at Southern Connecticut State University
