Moving target detection and tracking algorithm research content is very broad and complex applications, without and different target features directly affects the detection of selected tracking algorithm. So far still does not exist a universal algorithm for perfect can be suitable for various applications, so the detection and tracking of moving targets is still a valuable research subject of....

This paper presents a vision-based driver assistance system composing of vehicle detection using knowledge-based method and vehicle tracking using Kalman filtering. First, a preceding vehicle is localized by a proposed detection scheme, consisting of shadow detection and brake lights detection. Second, the possible vehicle region is extracted for verification. Symmetry analysis includes contour...

A methodology for both accurate and smooth contour line generation from Light Detection 1 and Ranging (LiDAR) point clouds is proposed in this paper. In order to improve the accuracy of 2 contour lines in the area of forests, constrained triangulation networks with break lines are then 3 constructed to generate contour lines. In break line extraction, a bi-threshold method for edge line 4 detec...

Research has shown that contour detection is impaired in the visual periphery for snake-shaped Gabor contours but not for circular and elliptical contours. This discrepancy in findings could be due to differences in intrinsic shape properties, including shape closure and curvature variation, as well as to differences in stimulus predictability and familiarity. In a detection task using only cir...
