Foreground detection separates foreground from background based on these changes taking place in the foreground. It is a set of techniques that typically analyze video sequences recorded in real time with a stationary camera.
In Schenkerian analysis, a structural level is a representation of a piece of music at a different level of abstraction, with levels typically including foreground, middleground, and background. [1] According to Schenker musical form is "an energy transformation, as a transformation of the forces that flow from background to foreground through ...
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 ...
Video matting is a technique for separating the video into two or more layers, usually foreground and background, and generating alpha mattes which determine blending of the layers. The technique is very popular in video editing because it allows to substitute the background, or process the layers individually.
Layering is a photographic composition technique that manipulates the foreground, subject or middle-ground, and background layers in a way that they all work together to tell a story through the image. [52] Layers may be incorporated by altering the focal length, distorting the perspective by positioning the camera in a certain spot. [53]
Space – area that an artist provides for a particular purpose. Space includes the background, foreground and middle ground, and refers to the distances or area(s) around, between, and within things. Texture – the way a three-dimensional work actually feels when touched, or the visual "feel" of a two-dimensional work
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]
Middle ground (also: middle-ground or middleground), an artistic space, located between background and foreground; Middleground (1947–1972), American Thoroughbred racehorse; Golden mean (philosophy), a desirable "middle ground" between two extremes. Argument to moderation, a logical fallacy that states that the "middle ground" is always correct
