Driven by human experts, today this process is very time consuming. An automation of both examination of suspicious areas and acquisition of fingerprints lead on the one hand to the covering of larger surfaces and on the other hand to significant speed up of the evidence collection. This work presents an experimental study on capabilities of chromatic white-light sensor (CWL) regarding the contact-less localization of latent fingerprints on differently challenging substrates. The fully automatic CWL-based system is implemented from the acquisition through the feature extraction right up to the classification. The key objective of the work is to develop a methodological approach for the quantitative evaluation of the localization success. Based on the proposed performance measures, the optimal system parameters such as scan resolution, extracted features and classification scheme are specified dependent on the surface material. Our experiments from an actual project with the sensor industry partner show convincing localization performance on easy-to-localize and adequate performance on moderate-to-localize substrates. The hard-to-localize substrates require further improvements of the localization system.}, language = {en} } @inproceedings{MakrushinHildebrandtFischeretal.2012, author = {Makrushin, Andrey and Hildebrandt, Mario and Fischer, Robert and Kiertscher, Tobias and Dittmann, Jana and Vielhauer, Claus}, title = {Advanced techniques for latent fingerprint detection and validation using a CWL device}, series = {In: Proceedings of SPIE 8436, 84360V. 2012.}, booktitle = {In: Proceedings of SPIE 8436, 84360V. 2012.}, doi = {10.1117/12.922235}, year = {2012}, abstract = {The technology-aided support of forensic experts while investigating crime scenes and collecting traces becomes a more and more important part in the domains of image acquisition and signal processing. The manual lifting of latent fingerprints using conventional methods like the use of carbon black powder is time-consuming and very limited in its scope of application. New technologies for a contact-less and non-invasive acquisition and automatic processing of latent fingerprints, promise the possibilities to inspect much more and larger surface areas and can significantly simplify and speed up the workflow. Furthermore, it allows multiple investigations of the same trace, subsequent chemical analysis of the residue left behind and the acquisition of latent fingerprints on sensitive surfaces without destroying the surface itself. In this work, a FRT MicroProf200 surface measurement device equipped with a chromatic white-light sensor CWL600 is used. The device provides a gray-scale intensity image and 3D-topography data simultaneously. While large area scans are time-consuming, the detection and localization of finger traces are done based on low-resolution scans. The localized areas are scanned again with higher resolution. Due to the broad variety of different surface characteristics the fingerprint pattern is often overlaid by the surface structure or texture. Thus, image processing and classification techniques are proposed for validation and visualization of ridge lines in high-resolution scans. Positively validated regions containing complete or sufficient partial fingerprints are passed on to forensic experts. The experiments are provided on a set of three surfaces with different reflection and texture characteristics, and fingerprints from ten different persons. © (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).}, language = {en} } @inproceedings{FischerKiertscherGruhnetal.2012, author = {Fischer, Robert and Kiertscher, Tobias and Gruhn, Stefan and Scheidat, Tobias and Vielhauer, Claus}, title = {From Biometrics to Forensics: A Feature Collection and first Feature Fusion Approaches for latent Fingerprint Detection using a Chromatic White Light (CWL) Sensor}, series = {In: Communications and multimedia security : 13th IFIP TC 6 TC 11 international conference ; proceedings / CMS 2012, Canterbury, UK, September 3 - 5, 2012}, booktitle = {In: Communications and multimedia security : 13th IFIP TC 6 TC 11 international conference ; proceedings / CMS 2012, Canterbury, UK, September 3 - 5, 2012}, editor = {De Decker, Bart}, publisher = {Springer}, address = {Berlin}, isbn = {978-3-642-32804-6}, doi = {10.1007/978-3-642-32805-3_21}, pages = {207 -- 210}, year = {2012}, abstract = {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 density-based 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.}, language = {en} } @inproceedings{HerrmannMakrushinDittmannetal.2012, author = {Herrmann, Enrico and Makrushin, Andrey and Dittmann, Jana and Vielhauer, Claus}, title = {Driver/passenger discrimination for the interaction with the dual-view touch screen integrated to the automobile centre console}, series = {Image processing: algorithms and systems X; and parallel processing for imaging applications II : 23 - 25 January 2012, Burlingame, California, United States ; proceedings ; [part of] IS\&T/SPIE electronic imaging science and technology]}, booktitle = {Image processing: algorithms and systems X; and parallel processing for imaging applications II : 23 - 25 January 2012, Burlingame, California, United States ; proceedings ; [part of] IS\&T/SPIE electronic imaging science and technology]}, editor = {Egiazarian, Karen O.}, publisher = {SPIE}, address = {Bellingham, Wash.}, isbn = {978-0-8194-8942-5}, doi = {10.1117/12.907925}, pages = {Art. 82950W}, year = {2012}, language = {en} } @inproceedings{HildebrandtKiltzSturmetal.2012, author = {Hildebrandt, Mario and Kiltz, Stefan and Sturm, Jennifer and Dittmann, Jana and Vielhauer, Claus}, title = {High-resolution printed amino acid traces: a first-feature extraction approach for fingerprint forgery detection}, series = {Media watermarking, security, and forensics 2012 : 23 - 25 January 2012, Burlingame, California, United States ; proceedings ; [part of] IS\&T/SPIE electronic imaging, science and technology}, booktitle = {Media watermarking, security, and forensics 2012 : 23 - 25 January 2012, Burlingame, California, United States ; proceedings ; [part of] IS\&T/SPIE electronic imaging, science and technology}, publisher = {SPIE}, address = {Bellingham, Wash.}, isbn = {978-0-8194-8950-0}, doi = {10.1117/12.909072}, year = {2012}, language = {en} } @inproceedings{JankowHildebrandtKiltzetal.2012, author = {Jankow, Mathias and Hildebrandt, Mario and Kiltz, Stefan and Sturm, Jennifer and Vielhauer, Claus}, title = {Performance analysis of digital cameras versus chromatic white light (CWL) sensors for the localization of latent fingerprints in crime scenes}, series = {Optics, photonics, and digital technologies for multimedia applications II : 17 - 18 April 2012, Brussels, Belgium ; [part of SPIE Photonics Europe]}, booktitle = {Optics, photonics, and digital technologies for multimedia applications II : 17 - 18 April 2012, Brussels, Belgium ; [part of SPIE Photonics Europe]}, publisher = {SPIE}, address = {Bellingham, Wash.}, isbn = {978-0-8194-9128-2}, year = {2012}, language = {en} } @inproceedings{KiltzDittmannVielhauer2012, author = {Kiltz, Stefan and Dittmann, Jana and Vielhauer, Claus}, title = {Beweissichere Daten in der digitalisierten Forensik}, series = {D-A-CH Security 2012 : Bestandsaufnahme - Konzepte - Anwendungen - Perspektiven ; [Arbeitskonferenz ; Konstanz, 25. und 26.
