The filter is equipped with three terms designed to perform three different tasks. The first term is an anisotropic diffusion term which is derived from a locally adaptive<jats:italic>p<\/jats:italic>-laplacian functional. The second term is an enhancement term or a shock term which imparts a shock effect at the edge points making them sharp. The third term is a reactive term which is derived based on the maximum a posteriori (MAP) estimator and this term helps the diffusive term to perform a Gamma distributive data-dependent multiplicative noise removal from images. And moreover, this reactive term ensures that deviation of the restored image from the original one is minimum. This proposed filter is compared with the state-of-the-art restoration models proposed for data-dependent multiplicative noise.<\/jats:p>","DOI":"10.1155\/2014\/981932","type":"journal-article","created":{"date-parts":[[2014,6,1]],"date-time":"2014-06-01T21:15:09Z","timestamp":1401657309000},"page":"1-8","source":"Crossref","is-referenced-by-count":1,"title":["Image Enhancement under Data-Dependent Multiplicative Gamma Noise"],"prefix":"10.1155","volume":"2014","author":[{"given":"Jidesh","family":"Pacheeripadikkal","sequence":"first","affiliation":[{"name":"Department of Mathematical and Computational Sciences, National Institute of Technology, Karnataka 575025, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bini","family":"Anattu","sequence":"additional","affiliation":[{"name":"Department of Electronics and Communications Engineering, National Institute of Technology, Karnataka 575025, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"98","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1109\/34.56205"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1155\/2012\/750146"},{"key":"3","year":"2013","journal-title":"IEEE Transactions on Cybernetics"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-642-24785-9_17"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.4208\/nmtma.2013.mssvm15"},{"issue":"1\u20134","key":"6","first-page":"259","volume":"60","year":"1992","journal-title":"Physica D: Nonlinear Phenomena"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1137\/S1064827599351751"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1137\/060671814"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvcir.2009.10.006"},{"key":"10","first-page":"103","volume-title":"Multiplicative denoising and deblurring: theory andalgorithms","year":"2003"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.1155\/2010\/250768"},{"issue":"1","key":"12","first-page":"22","volume":"2","year":"2009","journal-title":"SIAM Journal on Imaging Sciences"},{"key":"14","doi-asserted-by":"publisher","DOI":"10.1016\/j.compeleceng.2014.03.013"},{"issue":"4","key":"15","doi-asserted-by":"crossref","first-page":"919","DOI":"10.1137\/0727053","volume":"27","year":"1990","journal-title":"SIAM Journal on Numerical Analysis"},{"issue":"2","key":"16","doi-asserted-by":"crossref","first-page":"590","DOI":"10.1137\/0731032","volume":"31","year":"1994","journal-title":"SIAM Journal on Numerical Analysis"},{"key":"18","doi-asserted-by":"publisher","DOI":"10.1504\/IJSISE.2011.044541"},{"key":"19","doi-asserted-by":"publisher","DOI":"10.1016\/j.compeleceng.2012.03.017"},{"issue":"1","key":"21","doi-asserted-by":"crossref","first-page":"12","DOI":"10.1016\/0021-9991(88)90002-2","volume":"79","year":"1988","journal-title":"Journal of Computational Physics"},{"key":"22","year":"2007"},{"key":"23","doi-asserted-by":"publisher","DOI":"10.1109\/TIP.2003.819861"}],"container-title":["Applied Computational Intelligence and Soft Computing"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/acisc\/2014\/981932.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/acisc\/2014\/981932.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/acisc\/2014\/981932.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2017,6,22]],"date-time":"2017-06-22T14:09:50Z","timestamp":1498140590000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.hindawi.com\/journals\/acisc\/2014\/981932\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014]]},"references-count":20,"alternative-id":["981932","981932"],"URL":"https:\/\/doi.org\/10.1155\/2014\/981932","relation":{},"ISSN":["1687-9724","1687-9732"],"issn-type":[{"value":"1687-9724","type":"print"},{"value":"1687-9732","type":"electronic"}],"subject":[],"published":{"date-parts":[[2014]]}}}
