Title: Innovations of Yang Liu in Crowd Anomaly Detection
Introduction
Yang Liu is an accomplished inventor based in Medford, MA (US). He has made significant contributions to the field of video security systems, particularly in the area of crowd anomaly detection. His innovative approach utilizes advanced electronic processing techniques to enhance security measures in various environments.
Latest Patents
Yang Liu holds a patent for a groundbreaking invention titled "Crowd Anomaly Detection." This patent describes a video security system that includes an electronic processor designed to detect anomalies by analyzing video data captured through an image sensor. The system determines the number of people detected in multiple frames of the video data. For each moment t, the electronic processor calculates an average number of people n over a specified time interval (t-Δt, t), where Δt is greater than or equal to the moment t. The processor updates a histogram based on the average number of people for each non-overlapping time interval Δt. If the histogram indicates that the probability ρ of the average number of people n over the time interval (t-Δt, t) falls below a predetermined threshold probability ρ*, the electronic processor generates an alert to indicate that an anomalous crowd size has been detected. This innovative system enhances the ability to monitor and respond to unusual crowd behaviors effectively.
