Background subtraction is any technique which allows an image's foreground to be extracted for further processing (object recognition etc.). Many applications do not need to know everything about the evolution of movement in a video sequence, but only require the information of changes in the scene, because an image's regions of interest are ...

For example, the foreground might be in focus while the middle-ground and background are out-of-focus. When avoiding deep focus is used specifically for aesthetic effect—especially when the subject is in sharp focus while the background is noticeably out-of-focus—the technique is known as bokeh. [2]
A front projection effect is an in-camera visual effects process in film production for combining foreground performance with pre-filmed background footage. In contrast to rear projection, which projects footage onto a screen from behind the performers, front projection projects the pre-filmed material over the performers and onto a highly reflective background surface.
Mattes are used in photography and special effects filmmaking to combine two or more image elements into a single, final image. Usually, mattes are used to combine a foreground image (e.g. actors on a set) with a background image (e.g. a scenic vista or a starfield with planets). In this case, the matte is the background painting.
The foreground, middle ground and background are all defined by objects, animals, landscape, humans, and skylines. Hicks almost always painted outdoor scenes, in which the light source is the sun or sky.
The foreground is in focus, but slightly smudged; the middle ground has sharp, clear edges and well defined subjects, and the background fades into the distance, becoming more and more blurry the farther back the eye travels. He makes the middle ground section more clear, mimicking the effect of a camera.
