Facial anthropometry as an evidential tool in forensic image comparison
… be used in certain circumstances to facilitate comparison of a photograph of a suspect with the potential offender portrayed in video surveillance crime footage. Anthropometry does not have the same success rate in identification as DNA or fingerprinting. However, these types of evidence are not …

Person Identification in a Legal Setting
… an attempt to optimise identification from CCTV images, expert evidence based on forensic image comparison may be provided in court. However, forensic image comparison techniques suffer from a major shortcoming. There is a lack of scientific evidence to support their use. The focus of this thesis …

Efficient Local Comparison Of Images Using Krawtchouk Descriptors
<p>It is known that image comparison can prove cumbersome in both computational complexity and runtime, due to factors such as the rotation, scaling, and translation of the object in question. Due to the locality of Krawtchouk polynomials, relatively few descriptors are necessary to describe a …

Dorsal knuckle crease pattern: utility for forensic human identification
… The method used Photoshop© to visualise the image and a graphics tablet and stylus to trace the crease pattern. The pattern was coded using a system of letters and numbers and a qualitative assessment of crease depth (deep or faint) was also recorded. Reliability and repeatability of this …

Defect Detection in Selective Laser Melting
… photo every build layer. Data was analyzed using image comparison, signal amplitude, Fourier Transform, and Wavelet Decomposition.</p> <p>The developed print parameters reduced warpage in the part by better distributing heat throughout the build envelope. Reducing warpage enabled the lower portion …

The quantification of dorsal hand features of interest to assist forensic human identification
… within investigations related to paedophilic images transmitted via the Internet, where eye-witness and trace evidence are of limited value, and suspects must be identified via offender/suspect comparison. This has led to a requirement to investigate methods by which an individual may be …
