Background subtraction is a widely used operation in the video surveillance aimed at separating the expected scene the background from the unexpected entities the foreground . There are several problems related to this task mainly due to the blurred boundaries between background and foreground definitions. Therefore background subtraction is an open issue worth to be addressed under different points of view. In this paper we propose a comprehensive review of the background subtraction methods that considers also channels other than the sole visible optical one such as the audio and the infrared channels . In addition to the definition of novel kinds of background the perspectives that these approaches open up are very appealing in particular the multisensor direction seems to be well-suited to solve or simplify several hoary background subtraction problems. All the reviewed methods are organized in a novel taxonomy that encapsulates all the brand-new approaches in a seamless way. 1. Introduction Video background subtraction represents one of the basic low-level operations in the video surveillance .
