Provided is a method for generating a foreground in a foreground generating apparatus, the method including: extracting a plurality of foregrounds by applying a plurality of background models to an image, the plurality of background models having different ranges of a pixel variance value; generating an intersection foreground based on an intersection region among the extracted plurality of foregrounds; generating a union foreground based on a union region among the extracted plurality of foregrounds; and generating a final foreground based on the intersection foreground and the union foreground.
