A concept of initial data loss is introduced in order to increase capacity of the watermarking channel under high intensity additive white Gaussian noise. According to the concept some samples in predefined positions are ignored even though this produces errors in the initial stage of watermark embedding. The proposed method also exploits a new form of distribution of quantized samples where samples that interpret \u201c0\u201d and \u201c1\u201d have differently shaped probability density functions. Compared to well-known watermarking schemes, this provides an increase of capacity under noise attack and introduces a distinctive feature. Two criteria are proposed that express the feature numerically. The criteria are utilized by a procedure for estimation of a gain factor after possible gain attack. Several state-of-the-art quantization-based watermarking methods were used for comparison on a set of natural grayscale images. The superiority of the proposed method has been confirmed for different types of popular attacks.<\/jats:p>","DOI":"10.1155\/2014\/910808","type":"journal-article","created":{"date-parts":[[2014,9,11]],"date-time":"2014-09-11T17:04:27Z","timestamp":1410455067000},"page":"1-14","source":"Crossref","is-referenced-by-count":2,"title":["A New QIM-Based Watermarking Method Robust to Gain Attack"],"prefix":"10.1155","volume":"2014","author":[{"given":"Yevhen","family":"Zolotavkin","sequence":"first","affiliation":[{"name":"Research Center for Information and Systems, School of Information Sciences, University of Tampere, Kanslerinrinne 1, 33014 Tampere, Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2298-9553","authenticated-orcid":true,"given":"Martti","family":"Juhola","sequence":"additional","affiliation":[{"name":"Research Center for Information and Systems, School of Information Sciences, University of Tampere, Kanslerinrinne 1, 33014 Tampere, Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"year":"2007","key":"1"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1109\/TIP.2005.859378"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1109\/TIT.1983.1056659"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1155\/2013\/921270"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1109\/18.923725"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.1109\/TSP.2004.823468"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.1109\/TSP.2003.809366"},{"key":"14","doi-asserted-by":"publisher","DOI":"10.1109\/TMM.2008.2001361"},{"key":"15","doi-asserted-by":"publisher","DOI":"10.1109\/TSP.2006.881216"},{"key":"16","doi-asserted-by":"publisher","DOI":"10.1109\/TSP.2005.855407"},{"issue":"5","key":"18","doi-asserted-by":"crossref","first-page":"432","DOI":"10.1049\/iet-ipr.2013.0048","volume":"7","year":"2013","journal-title":"IET Image Processing"},{"key":"19","doi-asserted-by":"publisher","DOI":"10.1186\/1687-6180-2012-53"},{"key":"20","doi-asserted-by":"publisher","DOI":"10.1109\/TIFS.2011.2146250"},{"key":"21","doi-asserted-by":"publisher","DOI":"10.1109\/TIP.2010.2042646"},{"year":"1968","key":"26"}],"container-title":["International Journal of Digital Multimedia Broadcasting"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/ijdmb\/2014\/910808.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/ijdmb\/2014\/910808.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/ijdmb\/2014\/910808.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2017,6,22]],"date-time":"2017-06-22T16:17:26Z","timestamp":1498148246000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.hindawi.com\/journals\/ijdmb\/2014\/910808\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014]]},"references-count":15,"alternative-id":["910808","910808"],"URL":"https:\/\/doi.org\/10.1155\/2014\/910808","relation":{},"ISSN":["1687-7578","1687-7586"],"issn-type":[{"type":"print","value":"1687-7578"},{"type":"electronic","value":"1687-7586"}],"subject":[],"published":{"date-parts":[[2014]]}}}
