“…Using passive infrared imaging, a postmortem body tem-perature can be recorded noninvasively, without the risk of contamination (4). Additionally, passive infrared imaging of objects at the crime scene can provide new investigative leads, for example an indication of recent human contact or the time since a device was used (5).…”

“…As a result of improvements in technology and a decrease in costs, infrared imaging is an emerging technique for law enforcement and forensic investigators. Previous work showed that infrared imaging of crime scenes has serious potential for aiding forensic case work (4)(5)(6)(7). It is a nondestructive technique, which can reveal information invisible to the naked eye.…”

All objects radiate infrared energy invisible to the human eye, which can be imaged by infrared cameras, visualizing differences in temperature and/or emissivity of objects. Infrared imaging is an emerging technique for forensic investigators. The rapid, nondestructive, and noncontact features of infrared imaging indicate its suitability for many forensic applications, ranging from the estimation of time of death to the detection of blood stains on dark backgrounds. This paper provides an overview of the principles and instrumentation involved in infrared imaging. Difficulties concerning the image interpretation due to different radiation sources and different emissivity values within a scene are addressed. Finally, reported forensic applications are reviewed and supported by practical illustrations. When introduced in forensic casework, infrared imaging can help investigators to detect, to visualize, and to identify useful evidence nondestructively.

"Streaming video-based 3D reconstruction method compatible with existing monoscopic and stereoscopic endoscopy systems", Proc. SPIE, Vol. 8371, 837112 (2012) ABSTRACTCompared to open surgery, minimal invasive surgery offers reduced trauma and faster recovery. However, lack of direct view limits space perception. Stereo-endoscopy improves depth perception, but is still restricted to the direct endoscopic field-of-view. We describe a novel technology that reconstructs 3D-panoramas from endoscopic video streams providing a much wider cumulative overview. The method is compatible with any endoscope. We demonstrate that it is possible to generate photorealistic 3D-environments from mono-and stereoscopic endoscopy. The resulting 3D-reconstructions can be directly applied in simulators and e-learning. Extended to real-time processing, the method looks promising for telesurgery or other remote vision-guided tasks.
