Study Notes
Fingerprint Minutiae Types
- Ridge Ending: Point where a fingerprint ridge concludes; crucial for unique pattern identification.
- Island: Represents a small line situated between two ridge lines, contributing to ridge classification.
- Bridge: Formed by two horizontal ridges linked by a diagonal line, helping to analyze ridge flow.
- Eye: A distinctive circular shape formed by a single ridge in the center, significant for fingerprint analysis.
- Delta: Characterized by a triangular pattern of ridges, often used as a reference point in fingerprint classification.
- Bifurcation (Fork): Occurs when one ridge divides into two, serving as a key marker in fingerprint recognition.
- Dot: A feature where two ridges encircle a smaller dot, adding detail to fingerprint patterns.
- Spur: Identified as a curved line that hangs downward from an upper ridge, used in minutiae analysis.
- Double Bifurcation: A complex feature where the ridges split two times into two forks, enhancing detail in identification.
- Trifurcation: Happens when one ridge separates into three distinct lines, resembling a trident, and aids in fingerprint uniqueness.
