Image mosaicing is a powerful mean for obtaining a larger view of a scene than the available within a human eyes view or compact camera view. Homography matrix is the most suitable transformation model which is needed to create mosaiced images, and the estimation of the parameters of that model using RANSAC (Random Sample Consensus) is a key step in feature matching as it improves the stability of...
In this paper, we propose a robust and accurate algorithm based on a multimodal Sigma-Delta background estimation to extract the moving objects in image sequence of size 768 x 576 pixels taken from a static camera. Sigma-Delta estimation is used to compute two orders of temporal statistics for each pixel of the sequence providing a pixel-level decision framework. A serious limitation of this approach...
This paper describes the idea and the implementation of the robust algorithm dedicated to extraction of moving vehicles from real-time camera images for the evaluation of traffic parameters, such as the number of vehicles, their direction of movement and their approximate speed. The authors, apart from the careful selection of particular steps of the algorithm towards hardware implementation, also...
