Can DMD obtain a Scene Background in Color?

摘要

A background model describes a scene without any foreground objects and has anumber of applications, ranging from video surveillance to computationalphotography. Recent studies have introduced the method of Dynamic ModeDecomposition (DMD) for robustly separating video frames into a backgroundmodel and foreground components. While the method introduced operates byconverting color images to grayscale, we in this study propose a technique toobtain the background model in the color domain. The effectiveness of ourtechnique is demonstrated using a publicly available Scene BackgroundInitialisation (SBI) dataset. Our results both qualitatively and quantitativelyshow that DMD can successfully obtain a colored background model.
