After publication of this article (Rabiee et al. 2016), we noticed that some of the authors were inadvertently omitted from the author list. These authors, Moin Nabi, Vittorio Murino and Nicu Sebe, have been included in the corrected author list above. Additionally, the images in Fig. 1 have been removed from this article as we did not obtain the necessary permissions to publish them. This does not affect the scientific validity of the article.
