Fingerprints Delta
A delta is where three ridge lines meet at one point to create a triangular area (like the greek symbol delta δ). By definition, a delta is a triangular area at the edges of a fingerprint governed by the divergence of type lines. A delta is the ridge point nearest the type line divergence.
The delta point is a fingerprint pattern that resembles the greek letter delta in biometrics and fingerprint scanning.
Type lines are two diverging ridges usually coming into and splitting around an obstruction, such as a loop. Loops are further defined as having a core, delta, at least one recurving ridge. It is the result of two parallel lines diverging to flow around the loop or whorl. What is the delta pattern in fingerprints?
The delta pattern is a type of ridgeline pattern that is less common than loops and whorls. In image 1 at right you can see where the three sides of the delta form three. The delta point is a fingerprint pattern that resembles the greek letter delta in biometrics and fingerprint scanning. It is formed when one of the ridges splits.

Figure 1 provides an example of a fingerprint featuring a double core called a whorl (around which ridge lines circle) and a delta near the right bottom corner.
A chart illustrating fingerprint ridge patterns (arches, loops and whorls) and fingerprint ridge characteristics (core, ending ridge, short ridge, fork or bifurcation, delta, hook, eye, dot or. Delta is not on the ridge itself but at a point nearest to the divergent type lines. Several conventional approaches such as the poincare index method have been proposed; There are three basic fingerprint patterns:
It explains that fingerprints are categorized into three main patterns: A fingerprint pattern type where the ridges enter from one side, curve up and around and flow back out the side it entered. Forensically, a fingerprint core is defined as the innermost turning point where the fingerprint ridges form a loop, while the fingerprint delta is defined as the point where these. There is always one delta present in the loop pattern type.

It’s the point on a friction ridge where two type lines diverge at or near the. These patterns are defined by structures known as cores and deltas. The core of the print is the central area. A delta is the ridge point nearest the ty.
