Real time people detection on entrance gate using signal processing

In this we are going to a make security system that will help in counting the people available in a building or an area which is having an entrance gate in which whenever a people goes inside the building through the entrance gate it will show the count that certain count of people are inside the building and that some amount of people are going outside of building after 24 hours it will give an update about current amount of people staying inside the building till the night. In this we are using image processing using cvat software for datasets and using haar cascades algorithm for people detection and using signal processing it will give update on count of people.
