W artykule przedstawiono metodę obliczania miar ruchu dla inteligentnej analizy wideo. Obliczane są cztery miary: dwukierunkowa długość-łuku, kierunek-w-przód, kierunek-wstecz oraz krawędzie segmentów-ruchu. Wszystkie miary bazują na mapie przepływu obliczonej przy użyciu algorytmu przepływu optycznego. Segmenty-ruchu wykorzystują pola typu finite-time Lyapunov exponent (FTLE). Przeprowadzono eksperymentalne...
In this paper we present an algorithm for precise estimation of moving objects density (typically people and vehicles) in indoor and outdoor scenes. Automatic generation of the so-called density maps is based on video sequences acquired by surveillance systems. Our approach offers two types of solutions. The first one increments the accumulation table when a moving object is detected in a location...
This paper presents the design process of a gesture control system based on the Microsoft Kinect sensor. An environment enabling implementation of the integrated system using a variety of equipment and software was selected and prepared. A method for integrating the sensor with the Arduino environment has also been discussed. Algorithms for remote gesture control of the given servodrive angle and...
W artykule przedstawiono system sterowania gestem opartego na czujniku Microsoft Kinect. Omówiono najpopularniejsze środowiska umożliwiające realizację systemu zintegrowanego, wykorzystującego różnorodny sprzęt i oprogramowanie. Przygotowano algorytm bezdotykowego sterowania manipulatorem. Przedstawiono wyniki eksperymentów, przeprowadzonych w celu określenia dokładności i dobrania optymalnej metody...
The paper presents technical aspects related to the video computer analysis of people movement in the sales rooms. Automatic generation of the people density maps (also referred to as the “heat maps”) is helpful for the analysis of customers' and employees' behavior in sale and office rooms advertising effectiveness research or tracking movements. Generation of the density maps was realized with the...
A 1 MV linear transformer driver (LTD) generator has been manufactured by ITHPP and SEIV, and delivered to CEA/DIF/Polygone d'Expérimentation de Moronvilliers, in order to demonstrate the capability of this technology for flash X-ray radiography applications. This generator is composed of 10 cavities; each cavity includes 16 bricks representing two capacitors (GA 35436, 100kV, 8nF) and one multi-gaps...
