The extraction of photo-response non-uniformity (PRNU) noise has been so far indicated as a mean to identify sensor fingerprint. Such a fingerprint can be estimated from multiple images taken by the same camera by means of a de-noising filtering operation. In this paper, the authors propose a novel method for estimating the PRNU noise in source camera identification. In particular, a MMSE digital filter in the un-decimated wavelet domain, based on a signal-dependent noise model, is introduced and compared with others commonly adopted for this purpose. A theoretical framework and experimental results are provided and discussed.<\/p>","DOI":"10.4018\/jdcf.2010040102","type":"journal-article","created":{"date-parts":[[2010,4,30]],"date-time":"2010-04-30T16:16:20Z","timestamp":1272644180000},"page":"21-33","source":"Crossref","is-referenced-by-count":13,"title":["Estimate of PRNU Noise Based on Different Noise Models for Source Camera Identification"],"prefix":"10.4018","volume":"2","author":[{"given":"Irene","family":"Amerini","sequence":"first","affiliation":[{"name":"University of Florence, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Roberto","family":"Caldelli","sequence":"additional","affiliation":[{"name":"University of Florence, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vito","family":"Cappellini","sequence":"additional","affiliation":[{"name":"University of Florence, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Francesco","family":"Picchioni","sequence":"additional","affiliation":[{"name":"University of Florence, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alessandro","family":"Piva","sequence":"additional","affiliation":[{"name":"University of Florence, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2432","reference":[{"key":"jdcf.2010040102-0","doi-asserted-by":"publisher","DOI":"10.1016\/j.sigpro.2005.10.014"},{"key":"jdcf.2010040102-1","doi-asserted-by":"crossref","unstructured":"Bayram, S., Sencar, H.
