In mathematics the infimum of a subset of some set is the greatest element, not necessarily in the subset, that is smaller than all other elements of the subset.
In analysis the infimum or greatest lower bound of a set S of real numbers is denoted by inf(S) and is defined to be the biggest real number that is smaller than or equal to every number in S.
The notions of infimum and supremum are dual in the sense that

, an infimum is lower than the lowest possible real value (negative infinity) and a supremum is greater than the greatest possible real value (positive infinity).
Also, the infimum record can be a dummy target for temporary record locks.
considers the infimum and supremum to be part of the header or not.
In analysis the infimum or greatest lower bound of a set S of real numbers is denoted by inf(S) and is defined to be the biggest real number that is smaller than or equal to every number in S.
If the infimum value belongs to the set then we can say there is a smallest element in the set.
A infimum or greatest lower bound of S is an element l in P such that
The infimum of a set of images is defined as the greatest lower bound of the images, which for binary images is simply the pixel-wise minimum of the images.
For example, the infimum of 1 0 0 and 1 1 0 is 1 0 0 and the infimum of 1 1 0 and 0 1 1 is 0 1 0.
Similarly, the infimum would be red and not a mixture of the two colours.
