A Flow-Based Approach to Vehicle Detection and Background Mosaicking in Airborne Video
Conference Paper, Video Proceedings in conjunction with CVPR '05, Vol. 2, pp. 1202, June, 2005
Abstract
In this work, we address the detection of vehicles in a video stream obtained from a moving airborne platform. We propose a Bayesian framework for estimating dense optical flow over time that explicitly estimates a persistent model of background appearance. The approach assumes that the scene can be described by background and occlusion layers, estimated within an Expectation-Maximization framework. The mathematical formulation of the paper is an extension of our previous work where motion and appearance models for foreground and background layers are estimated simultaneously in a Bayesian framework.
