Driving assistance systems provide either safety or comfort functions. Such systems must evaluate the state of the world and take necessary actions. A preliminary step for evaluating the state of the world is to detect, track and classify scene objects. The classification step becomes especially important in complex urban traffic scenarios. In such scenarios the sensors of choice are vision based,...
There are many approaches to pedestrian detection in collision avoidance systems depending on the sensors (visible light, thermal infrared, radar, laser scanner) used for acquiring the data and the features (depth, shape, motion) used for detection. In this paper we present a method for shape based pedestrian detection in traffic scenes using a stereo vision system for acquiring the image frames and...
This paper presents the specifications and architecture for a stereovision sensor to be used in intersection assistance. The intersection problem imposes a wide field of view, reasonable accuracy for the typical intersection length, and fast response time. The image and 3D data provided by the low level routines are used to generate two kinds of environment descriptions - an unstructured description,...
In this work we analyze the effects of radiation-induced transient pulses on 6T SRAM cells operating in read mode. The critical charge of a memory cell during read mode is lower than in hold mode. For 1 to 0 upsets, this reduction reaches a factor x 1.5 for events produced by alpha particles; this factor is even higher for longer induced current pulses. The impact of events propagated through the...
