These approaches, however, often introduce excessive smoothing and can result in extensive visual feature blurring and thus are suitable only for images with low density noise. A marginal method to reduce impulsive noise is proposed in this paper that overcomes this limitation that is based on the following facts: (i) each channel in a color image is contaminated independently, and contaminative components are independent and identically distributed; (ii) in a natural image the gradients of different components of a pixel are similar to one another. This method divides components into different categories based on different noise characteristics. If an image is corrupted by salt-and-pepper noise, the components are divided into the corrupted and the noise-free components; if the image is corrupted by random-valued impulses, the components are divided into the corrupted, noise-free, and the possibly corrupted components. Components falling into different categories are processed differently. If a component is corrupted, modified total variation diffusion is applied; if it is possibly corrupted, scaled total variation diffusion is applied; otherwise, the component is left unchanged. Simulation results demonstrate its effectiveness.<\/jats:p>","DOI":"10.1155\/2017\/7635641","type":"journal-article","created":{"date-parts":[[2017,6,19]],"date-time":"2017-06-19T17:05:09Z","timestamp":1497891909000},"page":"1-18","source":"Crossref","is-referenced-by-count":1,"title":["Decision-Based Marginal Total Variation Diffusion for Impulsive Noise Removal in Color Images"],"prefix":"10.1155","volume":"2017","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8734-4954","authenticated-orcid":true,"given":"Hongyao","family":"Deng","sequence":"first","affiliation":[{"name":"School of Information & Software Engineering, University of Electronic Science and Technology of China, Chengdu 611731, China"},{"name":"College of Computer Engineering, Yangtze Normal University, Chongqing 408000, China"}]},{"given":"Qingxin","family":"Zhu","sequence":"additional","affiliation":[{"name":"School of Information & Software Engineering, University of Electronic Science and Technology of China, Chengdu 611731, China"}]},{"given":"Xiuli","family":"Song","sequence":"additional","affiliation":[{"name":"School of Computer Science and Technology, Chongqing University of Posts and Telecommunications, Chongqing 400065, China"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1109\/5.54807"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1109\/83.503905"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1109\/83.597278"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1016\/j.sigpro.2007.02.009"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1007\/11867586_7"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1016\/j.sigpro.2007.05.019"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1016\/j.sigpro.2015.10.030"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1016\/j.sigpro.2016.03.025"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.1007\/s11554-016-0599-6"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.1109\/TIP.2009.2019305"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.1007\/s11554-015-0500-z"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1016\/0167-2789(92)90242-F"},{"key":"14","doi-asserted-by":"publisher","DOI":"10.1109\/TIP.2005.864184"},{"key":"15","doi-asserted-by":"publisher","DOI":"10.1155\/2017\/2024396"},{"key":"16","doi-asserted-by":"publisher","DOI":"10.3934\/ipi.2016008"},{"key":"23","doi-asserted-by":"publisher","DOI":"10.1016\/j.camwa.2015.06.029"},{"key":"22","doi-asserted-by":"publisher","DOI":"10.1109\/TIP.2011.2158229"},{"key":"17","doi-asserted-by":"publisher","DOI":"10.1109\/tip.2005.857261"},{"key":"18","doi-asserted-by":"publisher","DOI":"10.1109\/TIP.2003.819861"},{"key":"19","doi-asserted-by":"publisher","DOI":"10.1109\/TIP.2011.2109730"},{"key":"20","first-page":"27","volume":"100","year":"2000","journal-title":"Ieice Technical Report Image Engineering"},{"key":"21","doi-asserted-by":"publisher","DOI":"10.3390\/s110303205"},{"key":"24","doi-asserted-by":"publisher","DOI":"10.1016\/s0167-8655(03)00016-3"}],"container-title":["Journal of Sensors"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/js\/2017\/7635641.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/js\/2017\/7635641.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/js\/2017\/7635641.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2017,6,19]],"date-time":"2017-06-19T17:05:14Z","timestamp":1497891914000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.hindawi.com\/journals\/js\/2017\/7635641\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017]]},"references-count":23,"alternative-id":["7635641","7635641"],"URL":"https:\/\/doi.org\/10.1155\/2017\/7635641","relation":{},"ISSN":["1687-725X","1687-7268"],"issn-type":[{"value":"1687-725X","type":"print"},{"value":"1687-7268","type":"electronic"}],"subject":[],"published":{"date-parts":[[2017]]}}}
