Abstract
Creating a background model for image processing to identify new foreground objects in successive video frames. A method includes providing a background image in a user interface. The method further includes receiving a first user input in the user interface that comprises an identification of one or more different regions within the background image. The method further includes receiving a second user input in the user interface that comprises a selection of an image change tolerance for each of the identified different regions. The method further includes providing the background image, information identifying the different regions, and the image change tolerances to an image processor. The background image, the information identifying the different regions, and the image change tolerances are used by the image processor to create a background model to thereby compare a successive image with the background model in order to identify foreground objects within the successive image.
