In this paper, we propose a robust and accurate algorithm based on a multimodal Σ-Δ background estimation to extract the moving objects in image sequence of size 768 x 576 pixels taken from a static camera. Σ-Δ estimation is used to compute two orders of temporal statistics for each pixel of the sequence providing a pixel-level(More)
Optical flow is a research topic of interest for many years. It has, until recently, been largely inapplicable to real-time applications due to its computationally expensive nature. This paper presents a new reliable flow technique which is combined with a motion detection algorithm, from stationary camera image streams, to allow flow-based analyses of(More)
