I. Introduction
In recent years, the demand for applications that determine the number of people is growing. Especially for those who do human detection using (AI) and computer vision. AI is the intelligence demonstrated by machines, as opposed to the natural intelligence displayed by humans and animals. It includes machine learning and computer vision. Computer vision is a form of AI in which computers can “see” the world, analyze visual data, and then make decisions about it or gain an understanding of the environment and the situation. Counting the number of people can have multiple uses, integration with room reservation applications, estimating people in a crowded area (mall, stadium, theater, and others), determining the parameters that must be set HVAC systems to achieve human thermal comfort in buildings. People counting is a crucial and challenging problem in visual surveillance. An accurate and real-time estimation of people in a shopping mall can provide valuable information for managers. Automatic monitoring of the number of people in public areas is also important for safety control and urban planning [1].
