The most commonly used method of pigment identification is to compare the spectral similarity between ones of unknown target and ones in spectral library, which requires a comprehensive and complete spectral library and is based on overall shape of the spectrum. To a certain extent, it may ignore some of the key absorption characteristics of the spectrum. Methods: A novel spectral matching method was proposed based on the spectrum divided into subsections for identification according to the main ion absorption characteristics. Main works: (1) establishing a spectral library suitable for typical pigment identification of painting; (2) discussing the main components, as well as the absorption positions of the ions and functional groups contained in pigments frequently used by artists; (3) presenting a novel spectral matching algorithm carried on spectral subsections for pigment identification; (4) verifying the feasibility and applicability of proposed method by a Chinese painting and a fresco. Conclusions: The proposed method can correctly identify the main pigments or components contained in the mixed area, which is better than the traditional method and more convenient than the unmixing method, except for some limitations in detecting white and black pigments.<\/jats:p>","DOI":"10.3390\/rs12203415","type":"journal-article","created":{"date-parts":[[2020,10,18]],"date-time":"2020-10-18T21:26:06Z","timestamp":1603056366000},"page":"3415","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["A Novel Spectral Matching Approach for Pigment: Spectral Subsection Identification Considering Ion Absorption Characteristics"],"prefix":"10.3390","volume":"12","author":[{"given":"Yiyi","family":"Liu","sequence":"first","affiliation":[{"name":"School of Geomatics and Urban Spatial Informatics, Beijing University of Civil Engineering and Architecture, No.15 Yongyuan Road, Daxing District, Beijing 102616, China"},{"name":"Beijing Key Laboratory for Architectural Heritage Fine Reconstruction &amp; Health Monitoring, No.15 Yongyuan Road, Daxing District, Beijing 102616, China"}]},{"given":"Shuqiang","family":"Lyu","sequence":"additional","affiliation":[{"name":"School of Geomatics and Urban Spatial Informatics, Beijing University of Civil Engineering and Architecture, No.15 Yongyuan Road, Daxing District, Beijing 102616, China"},{"name":"Beijing Key Laboratory for Architectural Heritage Fine Reconstruction &amp; Health Monitoring, No.15 Yongyuan Road, Daxing District, Beijing 102616, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0942-629X","authenticated-orcid":false,"given":"Miaole","family":"Hou","sequence":"additional","affiliation":[{"name":"School of Geomatics and Urban Spatial Informatics, Beijing University of Civil Engineering and Architecture, No.15 Yongyuan Road, Daxing District, Beijing 102616, China"},{"name":"Beijing Key Laboratory for Architectural Heritage Fine Reconstruction &amp; Health Monitoring, No.15 Yongyuan Road, Daxing District, Beijing 102616, China"}]},{"given":"Zhenhua","family":"Gao","sequence":"additional","affiliation":[{"name":"School of Geomatics and Urban Spatial Informatics, Beijing University of Civil Engineering and Architecture, No.15 Yongyuan Road, Daxing District, Beijing 102616, China"},{"name":"Beijing Key Laboratory for Architectural Heritage Fine Reconstruction &amp; Health Monitoring, No.15 Yongyuan Road, Daxing District, Beijing 102616, China"}]},{"given":"Wanfu","family":"Wang","sequence":"additional","affiliation":[{"name":"The Conservation Institute of Dunhuang Academy, Dunhuang, Gansu 736200, China"},{"name":"National Research Center for Conservation of Ancient Wall Paintings and Earthen Sites, Dunhuang Academy, Dunhuang, Gansu 736200, China"}]},{"given":"Xiao","family":"Zhou","sequence":"additional","affiliation":[{"name":"Chinese Academy of Cultural Heritage, Beijing 100029, China"}]}],"member":"1968","published-online":{"date-parts":[[2020,10,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"104811","DOI":"10.1016\/j.microc.2020.104811","article-title":"Identification of green pigments and binders in late medieval painted wings from Norwegian churches","volume":"156","author":"Platania","year":"2020","journal-title":"Microchem.
