Zebra-Crossing Detection for the Partially Sighted
Zebra-crossings are useful road features for outdoor navigation in mobility aids for the partially sighted. In this paper, zebra-crossings are detected by looking for groups of concurrent lines, edges are then partitioned using intensity variation information. In order to tackle the ambiguity of the detection algorithm in distinguishing zebra-crossings and stair-cases, pose information is sough...
متن کاملZebra Crossing Detection from Aerial Imagery Across Countries
We propose a data driven approach to detect zebra crossings in aerial imagery. The system automatically learns an appearance model from available geospatial data for an examined region. HOG as well as LBPH features, in combination with a SVM, yield state of the art detection results on different datasets. We also use this classifier across datasets obtained from different countries, to facilita...
متن کاملSelf-Similarity based Zebra-crossing Detection for Intelligent Vehicle
A zebra-crossing detection method for intelligent vehicle is proposed in this paper. The method is performed on a bird-eye view image called inverse perspective mapping image. The complete method includes two phrases. First, a morphological filer followed by horizontal projection is applied to fast extract candidate zebra-crossing regions, where the size and structure information of zebra-cross...
متن کاملInjury Severity and Mortality of Adult Zebra Crosswalk and Non-Zebra Crosswalk Road Crossing Accidents: A Cross-Sectional Analysis
PRINCIPALS Over a million people worldwide die each year from road traffic injuries and more than 10 million sustain permanent disabilities. Many of these victims are pedestrians. The present retrospective study analyzes the severity and mortality of injuries suffered by adult pedestrians, depending on whether they used a zebra crosswalk. METHODS Our retrospective data analysis covered adult ...
متن کامل3d Zebra-crossing Reconstruction from Stereo Rig Images of a Ground-based Mobile Mapping System
Zebra-crossings are very specific road features that are less generalized when imaged at different scales. We aim to use zebra-crossings as control objects for georeferencing the images provided by a Mobile Mapping System (MMS) using the oriented aerial images of the same area. In this paper, we present a full automatic method for 3D zebra-crossing reconstruction from our MMS calibrated stereo ...
