In summer 2009 the SAR research group of the Center for Sensorsystems (ZESS) started a project to generate high resolution SAR data, which is acquired by a stationary receiver. As illuminator for our experiments the German TerraSAR-X satellite is used, which can generate frequency modulated signals with a bandwidth up to 300MHz. We intend to acquire the direct satellite signal and the backscatt...

Drowsiness and fatigue of automobile drivers reduce the drivers’ abilities of vehicle control, natural reflex, recognition and perception. Such diminished vigilance level of drivers is observed at night driving or overdriving, causing accident and pose severe threat to mankind and society. Therefore it is very much necessary in this recent trend in automobile industry to incorporate driver assi...

Existing iris recognition systems are heavily dependent on specific conditions, such as the distance of image acquisition and the stop-and-stare environment, which require significant user cooperation. In environments where user cooperation is not guaranteed, prevailing segmentation schemes of the iris region are confronted with many problems, such as heavy occlusion of eyelashes, invalid off-a...

The purpose of this study was to report variations of the cubital superficial vein patterns in the Korean subjects, which was investigated by using venous illuminator, AccuVein. The 200 Korean subjects were randomly chosen from the patients and staff of the Keimyung University Dongsan Medical Center in Daegu, Korea. After excluding the inappropriate cases for detecting venous pattern, we collec...

Passive Bistatic Radar (PBR), also known as Passive Coherent Location (PCL), uses illuminators of opportunity. Passive radar using signals in a single frequency network modulated according to the Digital Audio/Video Broadcasting (DAB/DVB) standards using orthogonal frequency division multiplexing (OFDM) has recently been of increasing interest. There has been considerable research to develop tr...
