Making Background Subtraction Robust to Sudden Illumination Changes

Julien Pilet, Christoph Strech and Pascal Fua

Introduction

Occlusion handling in Augmented Reality is related to background subtraction. We present here a background subtraction method that is very robust to illumination changes. We demonstrate it both for surveillance and AR tasks.
