Segmentation of Forensic Latent Fingerprint Images Lifted Contact-Less from Planar Surfaces with Optical Coherence Tomography

• Rethabile Khutlang, Fulufhelo Vincent Nelwamondo, Ann Singh
• 2015 IEEE 39th Annual Computer Software and…
• 2015

Lifting latent fingerprints through means that do not make contact with the surface where the fingerprint is imprinted, is advantageous in many ways. Some of these advantages include: being able to… (More)

Fingerprint recognition is an important security technique with a steadily growing usage for the identification and verification of individuals. However, current fingerprint acquisition systems have… (More)

Experimental verification and validation of a computer model for light–tissue interaction

• Aletta Elizabeth Karsten, Ann Singh, Max Braun
• Lasers in Medical Science
• 2011

Laser light is frequently used in both diagnostics and treatment of patients. For any laser treatment to be effective it is important to deliver the correct dose at the treatment site. Human skin… (More)

Diffuse Reflectance Spectroscopy Versus Mexameter(®) MX18 Measurements of Melanin and Erythema in an African Population.

• Caradee Yael Wright, Aletta Elizabeth Karsten, +4 authors Petrus A Karsten
• Photochemistry and photobiology

Melanin provides protection against excess exposure to solar ultraviolet radiation (UVR) and related adverse health effects. Diffuse reflectance spectroscopy (DRS) can be used to calculate cutaneous… (More)

Performance analysis of a Hybrid fingerprint extracted from optical coherence tomography fingertip scans

• Luke Nicholas Darlow, James Connan, Ann Singh
• 2016 International Conference on Biometrics (ICB)
• 2016

The Hybrid fingerprint is a local-quality-specific blend of the surface and internal fingerprints, extracted from optical coherence tomography scans. Owing to its origin, and the manner in which it… (More)

Diffuse reflectance spectroscopy as a tool to measure the absorption coefficient in skin: South African skin phototypes.

• Aletta Elizabeth Karsten, Ann Singh, Petrus A Karsten, Max Braun
• Photochemistry and photobiology
• 2013

In any laser skin treatment, the optical properties (absorption and scattering coefficients) are important parameters. The melanin content of skin influences the absorption of light in the skin. The… (More)
