In this paper we present a method to detect and track straight lane boundaries, using a forward-looking single camera mounted on-board. The method proved to be robust, even under varying lighting… (More)
This paper presents1 a multisensor surveillance system used inside an Automated Border Control (ABC) system (more specifically, an eGate). The system consists of two parts: counting the number of… (More)
We propose an efficient robust version of the Lucas–Kanade template matching algorithm. The robust weights used by the algorithm are based on evidence which is accumulated over many frames. We also… (More)
In this paper we present a background subtraction algorithm for a practical surveillance system, on a GPU. It utilizes a compressed non-parametric representation of the history of each pixel, using… (More)
Image streams from road surveillance cameras often show a poor quality for measuring the vehicle's speed. This paper discusses methods for detection and tracking of vehicles that 1) provides… (More)
In recent years, computer vision methods have been exploited in traffic surveillance systems to perform video image analysis, e.g. extracting statistical traffic information and detecting events.… (More)
The antibacterial effect of caprylic acid (35 and 50 mM) on Escherichia coli O157:H7 and total anaerobic bacteria at 39 degrees C in rumen fluid (pH 5.6 and 6.8) from 12 beef cattle was investigated.… (More)
This paper presents a data-oriented tracking framework which aims to recover the spatio-temporal trajectories for an unknown number of interacting objects appearing and disappearing at arbitrary… (More)
Achieving accurate pedestrian detection for practically relevant scenarios in real-time is an important problem for many applications, while representing a major scientific challenge at the same… (More)
