1. A method of using monocular depth cues in a single two dimensional image to improve depth perception in the image, said method comprising the steps of: obtaining an image, said image comprising one or more objects, each of said objects in the image being either in the foreground or the background of the image; segmenting said one or more objects in the image; identifying which of said objects are in the foreground and which of said objects are in the background of the image; increasing the brightness of one or more said foreground objects relative to the brightness of one or more of said background objects in the image; blurring one or more said background objects in said image, said steps of increasing and blurring operating to improve depth perception of the image; generating a shadow of one or more said foreground objects in the image; and casting the generated shadow on one or more said background objects in the image.
