Estimating the queue length at street intersections by using a movement feature space approach
Pablo Negri · IET Image Processing · 2014
This study aims to estimate the traffic load at street intersections obtaining the circulating vehicle number through image processing and pattern recognition. The algorithm detects moving objects in a street view by using level lines and generates a new feature space called movement feature space (MFS). The MFS generates primitives as segments and corners to match vehicle model generating hypotheses. The MFS is also grouped in a histogram configuration called histograms of oriented level lines (HO2 L). This work uses HO2 L features to validate vehicle hypotheses comparing the performance of different classifiers: linear support vector machine (SVM), non‐linear SVM, neural networks and boosting. On average, successful detection rate is of 86% with 10 − 1 false positives per image for highly occluded images.
