What are minutiae points?

Minutiae points (fig. 1) are the local ridge discontinuities, which are of two types: ridge endings and bifurcations. A good quality image has around 40 to 100 minutiae [1]. It is these minutiae points which are used for determining uniqueness of a fingerprint.

What are minutiae patterns?

In biometrics and fingerprint scanning, minutiae refers to specific plot points on a fingerprint. This includes characteristics such as ridge bifurcation or a ridge ending on a fingerprint.

What are examples of minutiae?

Minutiae is defined as small, trivial unimportant details. Minor details about an event that don’t really matter such as the color of the napkins are an example of minutiae.

How many minutiae points must match?

Fingerprints have usually 20 to 30 minutiae and two fingerprints are considered to be matched if they have more than 10 matched minutiae.

What are examples of minutiae in a fingerprint?

Terms in this set (12)

• ridge ending. where the lines in the fingerprint pattern end or stop.
• island of short ridge. small line within two lines.
• bridge. two horizontal lines with diagonal connection.
• eye or enclosure. one line that forms a circle shape in the middle.
• delta.
• bifurcation or fork.
• dot.
• spur.

What are minutiae give three examples?

small line within two lines. bridge. two horizontal lines with diagonal connection. eye or enclosure. one line that forms a circle shape in the middle.

What does minutiae mean in science?

Minutiae. Minutiae are, in everyday English, minor or incidental details. In biometrics and forensic science, minutiae are major features of a fingerprint, using which comparisons of one print with another can be made.

What is the definition of minutiae in geography?

What is the definition of minutiae? Minutiae can be defined as the points where the ridge lines end or fork. So the minutiae points are the local ridge discontinuities and can be of many types. Ridge ending is the point where the ridge ends suddenly. Ridge bifurcation is the point where a single ridge branches out into two or more ridges.

What is a fingerprint minutiae point?

These minutiae points are used to determine the uniqueness of a fingerprint image. A good quality fingerprint image can have 25 to 80 minutiae depending on the fingerprint scanner resolution and the placement of finger on the sensor. What is the definition of minutiae? Minutiae can be defined as the points where the ridge lines end or fork.

What is minutiae in biometrics?

In biometrics and fingerprint scanning, minutiae refers to specific plot points on a fingerprint. This includes characteristics such as ridge bifurcation or a ridge ending on a fingerprint.

What is the difference between Ridge discontinuities and minutiae?

Minutiae can be defined as the points where the ridge lines end or fork. So the minutiae points are the local ridge discontinuities and can be of many types. Ridge ending is the point where the ridge ends suddenly. Ridge bifurcation is the point where a single ridge branches out into two or more ridges.
