This paper presents three applications for mobile phones dedicated to pedestrians, cyclists, motorcyclists, and car drivers, i.e., generally to various road users in order to assist them with innovative control of traffic flow – thus to substantially improve the traffic safety. The prepared software processes in real time a video sequence acquired with a camera built-in a smartphone. The first application...
In this paper a video processing procedure for automatic detection of pedestrians is presented. It is planned to use it as a part of the automotive night vision system. Generally, such systems are either passive (i.e. those based on thermal vision) or active (i.e. equipped with illuminators and near infrared cameras). Passive systems provide a large range of detection, while their active counterparts,...
W artykule przedstawiono trzy systemy elektroniczne do automatycznego usprawniania i poprawy bezpieczeństwa ruchu drogowego. Pierwszy system wspomaga kierowców w ruszaniu pojazdami sprzed sygnalizacji świetlnej po zmianie świateł z czerwonego na zielone bez niepotrzebnych przestojów. Drugi system wymusza spontaniczne dostosowanie się kierowców do tzw. „metody zamka błyskawicznego” w sytuacjach, kiedy...
In this paper an analysis and implementation of the algorithm for detecting and counting people in video surveillance systems is presented. First, we recapitulate methods which can be used for people counting. Next, we concentrate on our MATLAB/Simulink model for detecting people, who are passing under a camera positioned vertically down at the entrance to the monitored area (e.g., a building). The...
This paper presents techniques for fast prototyping of real-time hardware / software video processing systems for urban surveillance monitoring equipment. During the experimental research the evaluation module with the TMS320DM6437 signal processor programmed with the use of the Code Composer Studio and Matlab / Simulink environments has been used. Analyzed algorithms can support the work of monitoring...
In this paper we propose procedures for detection and recognition of main groups of vertical road signs. The algorithm is intended for the use in vehicles, thus it is optimized to work in real-time. The described recognition process consists of several following stages. At first we are reducing the number of colors using the minimum variance quantization and changing the representation of an input...
