Abstract
Background subtraction is a simple and effective method to detect anomalous regions in images. In spite of the effectiveness, it cannot be used with an active (moving) camera head because the background image varies with camera-parameter control. This paper presents a background subtraction method with pan-tilt-zoom control. The proposed method consists of an omnidirectional background model called appearance sphere and parallax free sensing. Based on this model, precise background images can be generated and background subtraction can be performed for any combination of pan-tilt-zoom parameters without restoring 3D scene information
