The wearable video system supports decision making through analyzing video images. Because personnel who wear the system or the object monitored is always moving, the technology of motion detection and target contour extraction used in the wearable video system are studied. First, the frequently-used algorithms for motion detection are studied, including frame difference method and background subtraction...
In current license plate recognition, there are many problems because of the complex, irregular motion and blur license plate. This paper presents a license tilt detection method, and to improve overall system performance and reliability, proposes some detection algorithms: gravity center method, Hough transform, the method of put vertexes into a line. Simply described their processes, at the same...
