Abstract
An image processing device for the detection and suppression of shadows in a camera image of a surveilled scene, the camera image optionally showing static objects with static shadow regions and moving objects with dynamic shadow regions, includes a long-term module, which is designed to generate a long-term reference image of the surveilled scene by evaluating a long-term observation of a particular scene, a mid-term module, which is designed to generate a mid-term reference image of the surveilled scene by evaluating a mid-term observation of the particular scene, and a shadow detection module, which is designed to process camera image—using information technology—with long-term reference image and mid-term reference image, in order to detect and suppress shadows.
