A method, medium, and apparatus with estimation of background changes. The method includes generating an edge map based on a pre-learned background image, and calculating a value representing the similarity between a foreground image extracted from an input image and the generated edge map and estimating a background change in the input image based on the calculated value. Therefore, the method can reduce the effect of disturbances caused by the implementation environment of an image-based intrusion detection system and uncontrollable device defects, which, in turn, reduces false alarms. |
