A SHADOW REJECTION ALGORITHM FOR VEHICLE PRESENCE DETECTION
Jiang Zifeng · 1998
In this paper, the author presents an integrated algorithm for shadow rejection. Shadow definitions and properties are first presented followed by an analysis of shadow rejection features. These include: 1) true variance and truncated variance, 2) horizontal, vertical and symmetric edges, and 3) curve and contour. The algorithm was tested with results indicating that the algorithm rejected over 50% of various moving shadows and over 80% of static shadows in real time.
