In

philately , a**line pair**is acoil pair ofpostage stamp s bearing an inked line between the two stamps. There are at least two kinds of these.A

**guide line pair**has aguide line between the stamps. Since the guide lines are deliberately incised into the plate, they will generally be sharp and clear.A

**joint line pair**has ajoint line between the stamps, deriving fromthe seam in the cylindrical plate used to print the stamps. These lines are somewhat smeared in appearance.---------------------------

**In image processing**In

image processing , the description of aline pair is this: on a test pattern consisting of closely spaced black parallel lines on a white background, aline pair is one black line together with the white space on one side of it. When photographers say "lines of resolution", they mean line pairs. In television and video, one line pair equals two TV lines orpixels , of resolution.
