The forgotten Indian pioneers of fingerprint science
While researching on the history of fingerprinting, we came across several archive records which throw light on the key role played by two Indian police officers, SubInspectors Azizul Haque and Hem Chandra Bose, in the advancement of the science of fingerprints. The so-called Henry’s System of Fingerprint Classification was actually worked out by them. The world’s first fingerprint bureau was s...
متن کاملFingerprint 1 Fingerprint 2 Fingerprint 3 Fingerprint 7 Fingerprint
Joint Fourier transform correlation is an analog optical signal processing technique capable of comparing several two-dimensional images. We show that selected spectral domain binary thresholds, obtained through simulation, signiicantly improve the performance of an optical implementation of the joint transform correlator. In doing so we establish empirically the existence of well deened optima...
متن کاملAn Automatic Fingerprint Classification Algorithm
Manual fingerprint classification algorithms are very time consuming, and usually not accurate. Fast and accurate fingerprint classification is essential to each AFIS (Automatic Fingerprint Identification System). This paper investigates a fingerprint classification algorithm that reduces the complexity and costs associated with the fingerprint identification procedure. A new structural algorit...
متن کاملA Robust Strucutural Fingerprint Restoration
Fast and accurate ridge detection in fingerprints is essential to each AFIS (Automatic Fingerprint Identification System). Smudged furrows and cut ridges in the image of a finger print are major problems in any AFIS. This paper investigates a new online ridge detection method that reduces the complexity and costs associated with the fingerprint identification procedure. The noise in fingerprint...
