We present the problem of sample preparation as well as capturing and processing of images for automatic measurements of diameters, areas and perimeters of early wood vessels. After testing various methods of sample preparation we found out that the best results were obtained when the samples were sanded with paper of granulation 320 and the surface stained with black alcohol marker. Vessel lumina were then filled with white chalk dust, and finally the images were captured by a digital camera attached to a stereo microscope and saved in TIF format. We improved the images by using digital filters, converted them to binary images and defined measurement frames. The results confirmed that the image analysis system Lucia G enables measurements of early wood vessel dimensions in ring porous species on macroscopic samples with satisfying accuracy"},{"@xml:lang":"sl","#text":"Sistem za analizo slike Lucia G smo uporabili za avtomatsko merjenje dimenzij trahej na makroskopskih vzorcih hrastovine (Quercus sp.).

Med različnimi načini priprave vzorcev smo najboljše rezultate dobili, ko smo jih zbrusili z brusnim papirjem granulacije 320 in površino obarvali s črnim alkoholnim flomastrom. V traheje smo nato vtrli prah bele krede in sliko posneli z digitalnim fotoaparatom nameščenim na stereo-mikroskop ter jo shranili v formatu TIF. Sliko smo obdelali z digitalnimi filtri, jo binarizirali in določili referenčni okvir za merjenje. Rezultati kažejo, da je s programom za analizo slike Lucia G mogoče pri venčastoporoznih vrstah na makroskopskem nivoju z zadovoljivo natančnostjo meriti dimenzije trahej ranega lesa"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:DOC-4PBIJ25S","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-4PBIJ25S"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-4PBIJ25S/2dbd1eb7-eabc-4a84-88db-e0e7d09efffd/PDF"},"edm:rights":{"@rdf:resource":"http://rightsstatements.org/vocab/InC/1.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Zveza lesarjev Slovenije"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:DOC-4PBIJ25S/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-4PBIJ25S"}}}}
