Real-time scene stabilization and mosaic construction

Abstract

We describe a real-time system designed to construct a stable view of a scene through aligning images of an incoming video stream and dynamically constructing an image mosaic. This system uses a video processing unit developed by the David Sarnoff Research Center called the Vision Front End (VFE-100) for the pyramid-based image processing tasks required to implement this process. This paper includes a description of the multiresolution coarse-to-fine image registration strategy, the techniques used for mosaic construction, the implementation of this process on the VFE-100 system, and experimental results showing image mosaics constructed with the VFE-100.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
