Chen's Algorithm

Chen’s Algorithm is a method used to detect when a moving object crosses a predefined boundary, such as a line or perimeter. It uses position data collected at different times to analyze the trajectory of the object. By calculating the relative positions and directions over consecutive points, the algorithm determines if the object has crossed the boundary line. This helps in applications like security or surveillance, where detecting crossings promptly and accurately is important. Essentially, it provides a systematic way to interpret movement patterns and confirm boundary violations based on tracking data.
