“…Ssk shows the skewness of surface height distribution and represents the degree of symmetry of the surface heights about the mean plane (Gruhn et al. ), and it is useful in monitoring for different types of wear conditions (Whitehouse ). If Ssk is greater than zero, it indicates the predominance of peaks; if Ssk is less than zero, it means that valley structures have more quantity (Tudose et al.…”

“…Statistical Features: For this study we have selected eight out of 40 statistical features we identified in prior work [3]. These features are derived from industrial standards such as ASME B46.1 / ISO 4287/1 / ANSI B.46.1, see [1,4].…”

“…This paper presents an approach, partly based on biometric methods, for a semi automated system for acquisition, detection, and localization of latent fingerprints using a chromatic white light (CWL) sensor, which is typically used in material science and industry. Based on previous work [2,3,5] new latent fingerprint detection features will be evaluated. Furthermore, certain fusion strategies, which are adopted from biometrics [8] are applied.…”

Application of non-invasive scan technologies for acquisition of latent fingerprints promise a better support of forensic and dactyloscopic experts when securing evidence at crime scenes. Furthermore, non-destructive acquisition preserve the chance of subsequent chemical and forensic analysis of left residue. Based on results of an ongoing research project with sensor industry partners, this paper presents a collection of 28 statistical, gradient-, and spectral densitybased features for latent fingerprint detection using low resolution scans. Within this work a chromatic white light (CWL) sensor is used for image acquisition. Furthermore, based on concepts of biometric fusion, a taxonomy for possible fusion strategies is presented and very first results for three different strategies on decision level are discussed. Experimental evaluation is performed based on scans of 1680 latent fingerprints on three different surfaces. The results show very good performance on planar, non-absorbing surfaces with uniform reflection characteristics with an detection rate of 2.51% in the best case. On the other hand difficulties are arising from surfaces with non-uniform/predictable reflection characteristics.

Roughness parameters of different abutment materials varied significantly. Precision of measurement differed according to the characteristics of the material used. White light interferometry could be recommended for measurement of TiN and AO. Confocal microscopy gave more precise measurements for Ma and CCM groups. The optical characteristics of the surface should be considered before choosing the examination method.
