Image processing device for monitoring system for processing of monitoring images of monitoring scene, has foreground image or actual moved foreground objects, and flow module, which is formed on basis of monitoring picture

摘要

The image processing device (1) has a foreground image or actual moved foreground objects, and a flow module (5), which is formed on basis of a monitoring picture to determine an optical flow field. A background module (6) is provided, which is formed on basis of the foreground image and the optical flow field to determine or update a scene background image. Independent claims are also included for the following: (1) a method for determining scene background image during processing of monitoring images; and (2) a computer program with program code unit.
