Since then, many algorithms and system architectures have been proposed, which use smart cameras to distribute functionality and save bandwidth. Still, smart cameras are rarely used in commercial systems and real installations. In this paper, we investigate the reason behind the scarce commercial usage of smart cameras. We found that, in order to achieve scalability, smart cameras put additional constraints on the quality of input data to the vision algorithms, making it an unfavourable choice for future multicamera systems. We recognized that these constraints can be relaxed by following a cloud based hub architecture and propose a cloud entity, SmartHub, which provides a scalable solution with reduced constraints on the quality. A framework is proposed for designing SmartHub system for a given camera placement. Experiments show the efficacy of SmartHub based systems in multicamera scenarios. <\/jats:p>","DOI":"10.1155\/2014\/757845","type":"journal-article","created":{"date-parts":[[2014,4,1]],"date-time":"2014-04-01T21:04:48Z","timestamp":1396386288000},"page":"757845","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":6,"title":["From Smart Camera to SmartHub: Embracing Cloud for Video Surveillance"],"prefix":"10.1177","volume":"10","author":[{"given":"Mukesh Kumar","family":"Saini","sequence":"first","affiliation":[{"name":"Multimedia Communications Research Laboratory (MCRLab), School of Electrical Engineering and Computer Science (EECS), University of Ottawa, Ottawa, ON, Canada, K1N 6N5"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pradeep K.","family":"Atrey","sequence":"additional","affiliation":[{"name":"Department of Applied Computer Science, The University of Winnipeg, Winnipeg, MB, Canada, R3B 2E9"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Abdulmotaleb El","family":"Saddik","sequence":"additional","affiliation":[{"name":"Multimedia Communications Research Laboratory (MCRLab), School of Electrical Engineering and Computer Science (EECS), University of Ottawa, Ottawa, ON, Canada, K1N 6N5"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2014,4,1]]},"reference":[{"key":"B1-2014-757845","doi-asserted-by":"publisher","DOI":"10.1145\/1236360.1236406"},{"first-page":"291","volume-title":"Proceedings of the 2nd CAD-Based Vision Workshop","author":"Sato K.","key":"B2-2014-757845"},{"key":"B3-2014-757845","doi-asserted-by":"publisher","DOI":"10.1109\/MC.2002.1033027"},{"key":"B4-2014-757845","doi-asserted-by":"publisher","DOI":"10.1109\/JPROC.2008.928742"},{"key":"B5-2014-757845","doi-asserted-by":"publisher","DOI":"10.1109\/ISM.2005.51"},{"first-page":"17","volume-title":"Proceedings of the International Conference on Multimedia and Expo (ICEM \u203203)","author":"Mallett J.","key":"B6-2014-757845"},{"volume-title":"Proceedings of the Workshop on Distributed Smart Cameras (DSC \u203206)","author":"Camillo Taylor J.","key":"B7-2014-757845"},{"key":"B8-2014-757845","doi-asserted-by":"publisher","DOI":"10.1109\/ICDSC.2007.4357500"},{"key":"B9-2014-757845","doi-asserted-by":"publisher","DOI":"10.1109\/MC.2006.55"},{"key":"B10-2014-757845","first-page":"299","volume-title":"Advances in Intelligent Systems and Applications","volume":"2","author":"Ye C.
