This paper presents an algorithm for background modeling and foreground detection that uses scaling coefficients, which are defined with a new color model called LRGB (Lightness-Red-Green-Blue). They are employed to compare two images by finding pixels with scaled lightness. Three backgrounds are used: verified background with pixels that are considered as background, testing background with pixels that are tested several times to check if they belong to the background, and final background that is a combination of the testing and verified background (the testing background is used in places where the verified background is not defined). If a testing background pixel matches pixels from previous frames (the match is tested using scaling coefficients), it is copied to the verified background, otherwise the pixel is set as the weighted average of the corresponding pixels of the last input images. After the background is computed, foreground objects are detected by using the scaling coefficients and additional criteria. The algorithm was evaluated using the SABS Dataset, Wallflower Dataset and a subset of the CDnet 2014 Dataset. The average F measure and sensitivity with the SABS Dataset were 0.7109 and 0.8725 respectively. In the Wallflower Dataset, the total number of errors was 5280 and the total F-measure was 0.9089. In the CDnet 2014 Dataset, the F-measure for the baseline test case was 0.8887 and for the shadow test case was 0.8300.

A method of delineating blood vessels by subtracting a tissue background image from an image of tissue plus intravascular contrast material that attenuates the X-ray photons. The background image is determined from a digitized image taken a few moments before injection of the contrast material. The resulting angiogram is a high-contrast image of the vessel. This subtraction technique allows extraction of a high-intensity signal from the superimposed background information. The image is thus the result of the differential absorption of X-rays by different tissues.
Detection of drugs that have been abused, overused, or misused, including legal and illegal drugs. Urine screening is the usual method of detection.
Inbred strains of animals that are genetically identical except at a single locus, or a few specified loci, so that their known genetic differences are expressed in the same genetic background. A congenic strain is produced by outbreeding a strain and then eliminating the background by many generations of backcrosses while maintaining the desired genetic differences by selection of progeny.

Designation for several severe forms of ichthyosis, present at birth, that are characterized by hyperkeratotic scaling. Infants may be born encased in a collodion membrane which begins shedding within 24 hours. This is followed in about two weeks by persistent generalized scaling. The forms include bullous (HYPERKERATOSIS, EPIDERMOLYTIC), non-bullous (ICHTHYOSIS, LAMELLAR), wet type, and dry type.
