So the object features can be emphasized while the undesired\ncontributions within the image due to light source nonuniformity can be\nreduced. Experimental results show that this new algorithm can gain better\nperformance in enhancing the local contrast of an image while maintaining\nits global appearance, in contrast to some representative algorithms.<\/jats:p>","DOI":"10.1515\/jisys-2012-0015","type":"journal-article","created":{"date-parts":[[2012,12,19]],"date-time":"2012-12-19T10:43:51Z","timestamp":1355913831000},"page":"349-362","source":"Crossref","is-referenced-by-count":0,"title":["A New Image Enhancement Algorithm via Wavelet Homomorphic Filtering Transform"],"prefix":"10.1515","volume":"21","author":[{"given":"Chao","family":"Li","sequence":"first","affiliation":[{"name":"College of Electronics and Information, Tongji University, Shanghai, 201804, P.\u00a0R.\u00a0China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guangyao","family":"Li","sequence":"additional","affiliation":[{"name":"College of Electronics and Information, Tongji University, Shanghai, 201804, P.\u00a0R.\u00a0China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yunlan","family":"Tan","sequence":"additional","affiliation":[{"name":"College of Electronics and Information, Tongji University, Shanghai, 201804; and College of Electronics and Information, Jinggangshan University, Jiangxi, 343009, P.\u00a0R.\u00a0China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xianglong","family":"Xu","sequence":"additional","affiliation":[{"name":"College of Electronics and Information, Tongji University, Shanghai, 201804, P.\u00a0R.\u00a0China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Huixian","family":"Duan","sequence":"additional","affiliation":[{"name":"College of Electronics and Information, Tongji University, Shanghai, 201804, P.\u00a0R.\u00a0China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"374","published-online":{"date-parts":[[2013,1,5]]},"container-title":["Journal of Intelligent Systems"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.degruyterbrill.com\/document\/doi\/10.1515\/jisys-2012-0015\/xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.degruyterbrill.com\/document\/doi\/10.1515\/jisys-2012-0015\/pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,12,5]],"date-time":"2025-12-05T17:17:32Z","timestamp":1764955052000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.degruyterbrill.com\/document\/doi\/10.1515\/jisys-2012-0015\/html"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2012,12,30]]},"references-count":0,"journal-issue":{"issue":"4","published-online":{"date-parts":[[2013,1,5]]},"published-print":{"date-parts":[[2012,12,30]]}},"alternative-id":["10.1515\/jisys-2012-0015"],"URL":"https:\/\/doi.org\/10.1515\/jisys-2012-0015","relation":{},"ISSN":["2191-026X","0334-1860"],"issn-type":[{"type":"electronic","value":"2191-026X"},{"type":"print","value":"0334-1860"}],"subject":[],"published":{"date-parts":[[2012,12,30]]}}}
