Using extensive experimental results we show how an online system with periodic noise estimation functionality can estimate the real frame noise even if the images are in JPEG format. We present the mathematical basis of the methodology and show in real content that we can have reliable measurements. We also present the results obtained on a real network camera and show that our method can provide a much better estimation of the noise standard deviation compared to common practice but comparable inter-channel and spatial intra-channel correlation estimates. We also provide some guidelines for capturing datasets necessary to apply computer vision tasks. Our approach exploits the well known stochastic linearization phenomenon which we prove that is present in our case. <\/jats:p>","DOI":"10.1142\/s0219467813500034","type":"journal-article","created":{"date-parts":[[2013,4,30]],"date-time":"2013-04-30T03:49:49Z","timestamp":1367293789000},"page":"1350003","source":"Crossref","is-referenced-by-count":0,"title":["ESTIMATION OF FRAME SEQUENCE NOISE WITH REMOVAL OF JPEG ARTIFACTS"],"prefix":"10.1142","volume":"13","author":[{"given":"VASILEIOS I.","family":"ANAGNOSTOPOULOS","sequence":"first","affiliation":[{"name":"Institute of Communications and Computer Science, National Technical University of Athens\u2013NTUA, 9, Iroon Polytechniou Street, Zografou 15773, Athens, Hellas, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"EMMANUEL S.","family":"SARDIS","sequence":"additional","affiliation":[{"name":"Institute of Communications and Computer Science, National Technical University of Athens\u2013NTUA, 9, Iroon Polytechniou Street, Zografou 15773, Athens, Hellas, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"THEODORA A.","family":"VARVARIGOU","sequence":"additional","affiliation":[{"name":"Institute of Communications and Computer Science, National Technical University of Athens\u2013NTUA, 9, Iroon Polytechniou Street, Zografou 15773, Athens, Hellas, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2013,5,3]]},"reference":[{"key":"rf1","doi-asserted-by":"publisher","DOI":"10.1109\/34.276126"},{"key":"rf2","volume-title":"The Mathematical Theory of Communication","author":"Shannon C.
