The widely used conventional touch-based fingerprint identification system has drawbacks like the elastic deformation due to nonuniform pressure, fingerprints collection time and hygiene. To overcome these drawbacks, recently the touchless fingerprint technology is gaining popularity and various touchless fingerprint acquisition solutions have been proposed. Nowadays due to the wide use of the smartphone...
Despite the wide use and success of touch-based fingerprint identification, elastic deformation is one of the primary reasons for false non-matching in most of the minutiae based automatic fingerprint identification systems. The main cause behind the large variation of the intra-class matching score is due to the non-uniform pressure applied during acquisition of fingerprint image. To avail deformation-free...
Encoding the local phase of the iris texture has come out as a promising way of generating extremely efficient feature vectors. Gabor wavelets yield a local phase representation distributed over several scales and orientations. One of the very promising attempts at obtaining a useful phase information is from the field of analytic signals and wavelets. The monogenic signal is an extension of the analytic...
Latent fingerprints on banknotes provide valuable information in forensic applications to identify suspects of robbery cases and counterfeiters. The image quality of latent fingerprints is poor due to the complex background of banknotes compared to live-scan images acquired in a controlled environment. An effective orientation field estimation algorithm is necessary for enhancing poor quality latents...
