Title: Bangjun Lei: Innovator in Digital Video Surveillance
Introduction
Bangjun Lei is a notable inventor based in Delft, Netherlands. He has made significant contributions to the field of digital video surveillance, holding a total of four patents. His work focuses on improving object tracking and identification in video sequences, which is crucial for enhancing surveillance systems.
Latest Patents
One of his latest patents involves a method for classifying an object in a video frame. In this digital video surveillance system, multiple processing stages are utilized to identify foreground regions that represent moving objects in a video sequence. An object tracking stage is also included to establish a correspondence between candidate objects in the current frame and those identified in previous frames. This allows for the calculation of the path taken by each foreground object, which is recorded in a trajectory database. To enhance tracking performance, the object tracking stage employs a state transitional object management scheme that determines whether a particular object should be tracked. The path information generated can be displayed on a video monitor of the surveillance system or made available to high-level applications.
Another significant patent by Lei focuses on identifying spurious regions in a video frame. Similar to his previous work, this patent employs various processing stages to identify moving objects. The object tracking stage identifies correspondences between current and previous frames, allowing for the calculation of object paths. The state transitional object management scheme is also utilized here to delete spurious objects based on their motion characteristics. This ensures that processing resources are not wasted on tracking unwanted artifacts, such as noise or random motion.
