Print media collections of considerable size are held by cultural heritage organizations and will soon be subject to digitization activities. However, technical content quality management in digitization workflows strongly relies on human monitoring. This heavy human intervention is cost intensive and time consuming, which makes automization mandatory. In this article, a new automatic quality assessment and improvement system is proposed. The digitized source image and color reference target are extracted from the raw digitized images by an automatic segmentation process. The target is evaluated by a reference-based algorithm. No-reference quality metrics are applied to the source image. Experimental results are provided to illustrate the performance of the proposed system. We show that it features a good performance in the extraction as well as in the quality assessment step compared to the state-of-the-art. The impact of efficient and dedicated quality assessors on the optimization step is extensively documented.
Vis plečiantis internete skelbiamam turiniui ir žinioms, bibliotekoms atsiveria galimybės teikti savo duomenis ir naujoviškai pristatyti savo rinkinius. Konceptualiai giminingą informaciją galima sieti semantiškai, taip praturtinant vartotojus gausesniais duomenų rinkiniais ir naujoviškomis paieškos galimybėmis, atsirandančiomis dėl medijoms, vietiniams metaduomenims ir išoriniams informacijos šaltiniams būdingų tarpusavio ryšių.
Šiame straipsnyje pristatomi CONTENTUS projekte plėtojami bibliotekoms ir multimedijos archyvams skirti sprendimai, susiję su įvairialypių duomenų šaltinių integravimo ir inovatyvių semantinės paieškos koncepcijų teikimo iššūkiais.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
