Counting of Passing Persons with Different Moving Ways in Horizontal View Scene

Abstract

Counting of passing persons in passage or corridor is considered important for security or various investigations. This paper proposes a method for automatic counting of moving persons with different moving ways in a horizontal view scene. Every gravitational center of a separated block in a frame for detecting motion is plotted in a plotting space. After that, movements of passing persons are detected by Hough transform without motion tracking. Intercepts and slopes of detected lines by Hough transform represent starting times when persons came into a scene and moving speeds of targets. Moving ways also can be recognized by measuring differences of moving speeds of detected persons. The experimental results showed that reliable detection and counting of passing persons were realized by the proposed method.
