The measurements were performed with a spatial resolution of 79 \u00b5m. In the present case, hyperspectral imaging was used to measure wood sample reflectance for light in the wavelength range between 380 and 1028 nm, with a resolution of approximately 0.6 nm. The work was performed with 34 samples collected from 34 trees of <jats:italic>Pinus pinea<\/jats:italic>. A total of 34,093 density points were used to create and validate a partial least-squares (PLS) regression that converts spectroscopic reflectance data into density values. The coefficient of determination value between the present method and X-ray microdensitometry is 0.810 with a root mean squared error of 6.54\u00d710<jats:sup>-2<\/jats:sup> g.cm<jats:sup>-3<\/jats:sup>.<\/jats:p>","DOI":"10.1515\/hf-2011-0258","type":"journal-article","created":{"date-parts":[[2012,9,3]],"date-time":"2012-09-03T14:53:11Z","timestamp":1346683991000},"page":"59-65","source":"Crossref","is-referenced-by-count":30,"title":["Measurement of intra-ring wood density by means of imaging VIS\/NIR spectroscopy (hyperspectral imaging)"],"prefix":"10.1515","volume":"67","author":[{"given":"Armando","family":"Fernandes","sequence":"first","affiliation":[{"name":"CITAB \u2013 Centre for the Research and Technology of Agro-Environmental and Biological Sciences, University of Tr\u00e1s-os-Montes e Alto Douro, Apartado 1013, 5001-801 Vila Real, Portugal"}]},{"given":"Jos\u00e9","family":"Lousada","sequence":"additional","affiliation":[{"name":"CITAB \u2013 Centre for the Research and Technology of Agro-Environmental and Biological Sciences, University of Tr\u00e1s-os-Montes e Alto Douro, Apartado 1013, 5001-801 Vila Real, Portugal"}]},{"given":"Jos\u00e9","family":"Morais","sequence":"additional","affiliation":[{"name":"CITAB \u2013 Centre for the Research and Technology of Agro-Environmental and Biological Sciences, University of Tr\u00e1s-os-Montes e Alto Douro, Apartado 1013, 5001-801 Vila Real, Portugal"}]},{"given":"Jos\u00e9","family":"Xavier","sequence":"additional","affiliation":[{"name":"CITAB \u2013 Centre for the Research and Technology of Agro-Environmental and Biological Sciences, University of Tr\u00e1s-os-Montes e Alto Douro, Apartado 1013, 5001-801 Vila Real, Portugal"}]},{"given":"Jo\u00e3o","family":"Pereira","sequence":"additional","affiliation":[{"name":"CITAB \u2013 Centre for the Research and Technology of Agro-Environmental and Biological Sciences, University of Tr\u00e1s-os-Montes e Alto Douro, Apartado 1013, 5001-801 Vila Real, Portugal"}]},{"given":"Pedro","family":"Melo-Pinto","sequence":"additional","affiliation":[{"name":"CITAB \u2013 Centre for the Research and Technology of Agro-Environmental and Biological Sciences, University of Tr\u00e1s-os-Montes e Alto Douro, Apartado 1013, 5001-801 Vila Real, Portugal"}]}],"member":"374","published-online":{"date-parts":[[2012,9,4]]},"container-title":["hfsg"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/www.degruyter.com\/view\/j\/hfsg.2013.67.issue-1\/hf-2011-0258\/hf-2011-0258.xml","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.degruyter.com\/document\/doi\/10.1515\/hf-2011-0258\/xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.degruyter.com\/document\/doi\/10.1515\/hf-2011-0258\/pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,1,6]],"date-time":"2023-01-06T15:27:26Z","timestamp":1673018846000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.degruyter.com\/document\/doi\/10.1515\/hf-2011-0258\/html"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2012,9,4]]},"references-count":0,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2012,7,18]]},"published-print":{"date-parts":[[2013,1,1]]}},"alternative-id":["10.1515\/hf-2011-0258"],"URL":"https:\/\/doi.org\/10.1515\/hf-2011-0258","relation":{},"ISSN":["1437-434X","0018-3830"],"issn-type":[{"value":"1437-434X","type":"electronic"},{"value":"0018-3830","type":"print"}],"subject":[],"published":{"date-parts":[[2012,9,4]]}}}
