What is the definition of a delta in fingerprint analysis?

In fingerprint analysis, a delta is defined as a specific fingerprint characteristic that refers to the point where two line segments of a ridge pattern converge or diverge. Deltas are crucial in the field of forensic science as they help in the classification and identification of different fingerprint patterns. When analyzing fingerprints, identifying deltas aids in determining the overall pattern classification, such as loops or whorls, and plays a significant role in comparing and matching fingerprints.

Understanding the significance of deltas in fingerprint analysis is fundamental for law enforcement and forensic investigations, as it provides key insights into the uniqueness of individuals' fingerprints and enhances the accuracy of identification processes.
