* Background, foreground, sideground and postground intellectual property, distinct forms of intellectual property assets
* Background subtraction, a technique in image processing and computer vision by which an image's foreground is extracted for further processing
* Figure–ground (perception), a humans' ability to separate foreground from background in visual images
* Foreground-background, a scheduling algorithm that is used to control execution of multiple processes on a single processor
* Foreground-background segmentation, a method for studying change blindness using photographs with distinct foreground and background scenery
* Foreground detection, a concept in computer vision to detect changes in image sequences
* Foreground and background in photography and cinematography, a principle important for
   * Depth of field, the distance between the nearest and farthest objects in a scene that appear acceptably sharp in an image
   * Deep focus, a technique using a large depth of field
   * Fill flash, to correctly expose the foreground and background objects
   * Photographic layering, a compositional technique
* Front projection effect, an in-camera visual effects process in film production for combining foreground performance with pre-filmed background footage
* Parallax scrolling, a scrolling technique in computer graphics, wherein background images move by the camera slower than foreground images, creating an illusion of depth
* Rear projection effect, an in-camera cinematic technique in film production for combining foreground performances with pre-filmed backgrounds
* Simple interactive object extraction, an algorithm used to extract foreground objects from color images and videos
* Structural level, an abstract representation of a piece of music.
