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 ...
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]
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]
Foreground-background is a scheduling algorithm that is used to control an execution of multiple processes on a single processor. It is based on two waiting lists, the first one is called foreground because this is the one in which all processes initially enter, and the second one is called background because all processes, after using all of their execution time in foreground, are moved to ...
Simple interactive object extraction (SIOX) is an algorithm for extracting foreground objects from color images and videos with very little user interaction. [1] It has been implemented as "foreground selection" tool in the GIMP (since version 2.3.3), as part of the tracer tool in Inkscape (since 0.44pre3), and as function in ImageJ and Fiji (plug-in).
A conventional OTS shot always has at least three layers of depth: the foreground, middle ground and background. [5] [3] The inclusion of a subject’s shoulder, and often the back of their head in the foreground, adds depth to the frame. [2]
Although the space may appear shallow on the picture plane of these paintings, depth is created through objects and objects size, and secondarily by light and shadows. The foreground, middle ground and background are all defined by objects, animals, landscape, humans, and skylines.
