Numerous methods are available to forensic scientists for detecting fingerprints in which the prints are treated with various agents to enhance the visual contrast between the print and the surface. In the present work, the spatial elemental imaging capabilities of micro-X-ray fluorescence (MXRF) were used to visualize fingerprint patterns based on inorganic elements present in the prints. A ma...

Cheiloscopy deals with examination of system of furrows on the red part of human lips. The present study was undertaken to classify lip prints, study their variations, determine the most common pattern in the study population, evaluate differences in lip prints between males and females and between different age groups, ascertain whether there is any hereditary pattern and thereby investigate t...

Background: Fast and secure identification processes in forensic odontology can be a very difficult process. Probably the most common techniques used are Dental, fingerprint and DNA comparisons. Since these techniques cannot always be used, it is necessary to apply different and less known techniques such as cheiloscopy. Due to its special features, lip groove can be used successfully in human ...

Daguerreotypes are sharply defined, highly reflective, one-of-a-kind photographs on silver-coated copper plates, packaged behind glass and kept in protective cases. Introduced in 1839 by Louis-Jacques-Mandé Daguerre, the daguerreotype process was the first commercially successful photographic process, and is distinguished by a remarkable clarity of pictorial detail. Daguerreotypes were popular ...

The PRINTS database houses a collection of protein fingerprints. These may be used to make family and tentative functional assignments for uncharacterised sequences. The September 2001 release (version 32.0) includes 1600 fingerprints, encoding approximately 10 000 motifs, covering a range of globular and membrane proteins, modular polypeptides and so on. In addition to its continued steady gro...

Aim and Objectives : The present study was aimed to nd gender differences in lip prints and rugae pattern and also to correlate particular lip print and rugae pattern. Methodology 150 individuals (75 male and 75 female) were included for the study. Lip prints were taken on the glued portion of cellophane strip and was stuck on the white bond paper. The grooves present on the middle portion of ...

Modern photoengraving methods can generate forged prints really similar to original ones. Till recently, in order to distinguish between these fakes and original prints, art historian specialized in art prints have been using only magnifiers (magnifying lenses). The aim of the present study was to set up a scientific method based on non-invasive techniques to find out differences between photoe...

To solve problems associated with conventional 2D fingerprint acquisition processes including skin deformations and print smearing, we developed a noncontact 3D fingerprint scanner employing structured light illumination that, in order to be backwards compatible with existing 2D fingerprint recognition systems, requires a method of unwrapping the 3D scans into 2D equivalent prints. For the latt...
