We propose a novel method to generate the Interval-Valued Intuitionistic Fuzzy Sets (IVIFS) from Interval-Valued Fuzzy Sets (IVFS). Given an input image in the gray level domain, first we construct a fuzzy image, and then each element of the image is converted to an interval-valued fuzzy element based on t-norms, t-conorms and the neighboring elements of that element. We then introduce an Interval-Valued Intuitionistic Fuzzy Generator (IVIFG) to construct the IVIFS for the given image. The optimized value for the negation parameter is determined based on a notion of the entropy of IVIFSs. Using this IVIF image, an intuitionistic fuzzy edge is introduced and finally this edge image is converted to a fuzzy and gray level edge image in the following stages of the proposed framework. Our experiments on a standard image database demonstrate the superiority of the proposed approach. In particular, our method shows a better performance compared to IVF case. Different t-norms, t-conorms as well as different neighboring sizes of each element of the image are used and compared.<\/jats:p>","DOI":"10.3233\/ifs-131099","type":"journal-article","created":{"date-parts":[[2019,12,2]],"date-time":"2019-12-02T18:49:59Z","timestamp":1575312599000},"page":"1309-1324","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":3,"title":["Interval-valued intuitionistic fuzzy generators: Application to edge detection"],"prefix":"10.1177","volume":"27","author":[{"given":"Fatemeh","family":"Afsari","sequence":"first","affiliation":[{"name":"Faculty of Mathematics and Computer Science, Shahid Bahonar University of Kerman, Kerman, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Esfandiar","family":"Eslami","sequence":"additional","affiliation":[{"name":"Faculty of Mathematics and Computer Science, Shahid Bahonar University of Kerman, Kerman, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pooya","family":"Eslami","sequence":"additional","affiliation":[{"name":"Professional Member, IEEE, Integrated Systems design Inc., Charlotte, NC, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2014,1]]},"container-title":["Journal of Intelligent &amp; Fuzzy Systems"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.3233\/IFS-131099","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.3233\/IFS-131099","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T09:37:02Z","timestamp":1777455422000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.3233\/IFS-131099"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014,1]]},"references-count":0,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2014,9]]}},"alternative-id":["10.3233\/IFS-131099"],"URL":"https:\/\/doi.org\/10.3233\/ifs-131099","relation":{},"ISSN":["1064-1246","1875-8967"],"issn-type":[{"value":"1064-1246","type":"print"},{"value":"1875-8967","type":"electronic"}],"subject":[],"published":{"date-parts":[[2014,1]]}}}
