Estimating the queue length at street intersections by using a movement feature space approach
(Institution of Engineering and Technology, 2014-07)
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 ...
Extração de feições retas com precisão subpixel: estudo comparativo entre três métodos
