The complementary nature of color and depth synchronized information acquired by low cost RGBD sensors poses new challenges and design opportunities in several applications and research areas. Here, we focus on background subtraction for moving object detection, which is the building block for many computer vision applications, being the first relevant step for subsequent recognition, classification, and activity analysis tasks. The aim of this paper is to describe a novel benchmarking framework that we set up and made publicly available in order to evaluate and compare scene background modeling methods for moving object detection on RGBD videos. The proposed framework involves the largest RGBD video dataset ever made for this specific purpose. The 33 videos span seven categories, selected to include diverse scene background modeling challenges for moving object detection. Seven evaluation metrics, chosen among the most widely used, are adopted to evaluate the results against a wide set of pixel-wise ground truths. Moreover, we present a preliminary analysis of results, devoted to assess to what extent the various background modeling challenges pose troubles to background subtraction methods exploiting color and depth information.
