One of the typical distortions in the background estimation methods is a change of lighting conditions, since each such change influences on the luminance of pixels in the captured images, which may be classified as the background. The global changes are relatively easy to compensate, but in practical applications the character of most of such changes is rather local. These changes may be caused e...
W artykule przedstawiono metodę wykorzystania algorytmu superrozdzielczości dla pojedynczej kamery rejestrującej obraz drogi. Pojazdy o rozmiarze mniejszym od jednego piksela pobudzają cały piksel, przez co estymacja ich położenia i prędkości jest utrudniona. Wykorzystanie algorytmu Spatio-Temporal Track-Before-Detect (ST-TBD) pozwala na śledzenie obiektów subpikselowych, jednak istnieją takie trajektorie,...
One of the major advantages of the video cameras' usage for tracking of vehicles is to reduce the costs of Intelligent Transport Systems. However, this requires the development of software techniques allowing an automatic extraction of the vehicle or group of vehicles from the current video frame, which is possible by using the background estimation methods, assuming a fixed camera installed over...
