The tree-ring curves were measured using two measurement methods: firstly manually on the traversing table using a stereo microscope with TSAPWin dendrochronolog-ical software and secondly in the LignoVision software (LV) from uploaded image files (scans, modified monographic scans and X-ray scans). Automatic image analysis was also tested in this software. Results showed that the tree-ring curves based on manual determination of printed-out photographs and scans using a stereo microscope on a traversing table and on manual determination of identical digital images in LignoVision matched to a large extent the data obtained by measuring the physical sample. The results were worse when tree-ring curves were measured from an X-ray scan, both using stereo microscope on a printed image, and using LignoVision. The automatic anal-ysis of the LignoVision software showed a high error rate. Finally, the results of measurements of individual image types and the possibilities of practical use of individual image records of dendro-chronological samples are discussed.<\/p>\n","protected":false},"author":4,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[403],"tags":[2670,2053,2669,2668,2671],"release_year":[],"ppma_author":[2017,2016,2018],"class_list":["post-3329","post","type-post","status-publish","format-standard","hentry","category-wood-research-volume-62-number-1-2017","tag-abies-alba-mill","tag-dendrochronology","tag-nondestructive-measurement","tag-tree-ring-curve-measurement","tag-x-ray-radiography"],"featured_image_src":null,"author_info":{"display_name":"Maro\u0161 Kov\u00e1\u010d","author_link":"https:\/\/www.woodresearch.sk\/cms\/author\/kovacvupc-sk\/"},"authors":[{"term_id":2017,"user_id":0,"is_guest":1,"slug":"andrea-nasswettrova","display_name":"Andrea Nasswettrov\u00e1","avatar_url":"https:\/\/secure.gravatar.com\/avatar\/?s=96&d=mm&r=g","0":null,"1":"","2":"","3":"","4":"","5":"","6":"","7":"","8":""},{"term_id":2016,"user_id":0,"is_guest":1,"slug":"sona-krivankova","display_name":"So\u0148a K\u0159iv\u00e1nkov\u00e1","avatar_url":"https:\/\/secure.gravatar.com\/avatar\/?s=96&d=mm&r=g","0":null,"1":"","2":"","3":"","4":"","5":"","6":"","7":"","8":""},{"term_id":2018,"user_id":0,"is_guest":1,"slug":"pavel-smira","display_name":"Pavel \u0160m\u00edra","avatar_url":"https:\/\/secure.gravatar.com\/avatar\/?s=96&d=mm&r=g","0":null,"1":"","2":"","3":"","4":"","5":"","6":"","7":"","8":""}],"_links":{"self":[{"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/posts\/3329","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/users\/4"}],"replies":[{"embeddable":true,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/comments?post=3329"}],"version-history":[{"count":1,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/posts\/3329\/revisions"}],"predecessor-version":[{"id":3331,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/posts\/3329\/revisions\/3331"}],"wp:attachment":[{"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/media?parent=3329"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/categories?post=3329"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/tags?post=3329"},{"taxonomy":"release_year","embeddable":true,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/release_year?post=3329"},{"taxonomy":"author","embeddable":true,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/ppma_author?post=3329"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
