Study of Interference Noise in multi-Kinect set-up

Kinect™, a low-cost multimedia sensing device, has revolutionized human computer interaction (HCI) by making various applications of human activity tracking affordable and widely available. Often multiple Kinects are used in imaging applications to improve the field of view, depth of field and uni-directional vision of a single Kinect. Unfortunately, multiple Kinects lead to IR Interference Noise (IR Noise, in short) in the depth map. In this paper we analyse the estimators for interference noise, survey various imaging techniques to mitigate the interference at source, and characterize them in parallel to a well-known classification system in telecom industry. Finally we compare their performance from reported literature and outline our on-going research to control interference noise by software shuttering.
