Aged skin: detection of alterations of major collagen types ratio by image processing of electron-optical dataAged skin: detection of alterations of major collagen types ratio by image processing of electron-optical data Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2015-10-242004enAutomated algorithms are developed in this paper based on digital signal processing to correlate electron-optical data from skin collagen fibrils with known sequence data. In particular, they detect alterations on the ratio of major collagen types in skin upon age. http://creativecommons.org/licenses/by/4.0/Micron335221–225 Zervakis Michalis Ζερβακης Μιχαλης Margaret Tzaphlidou Elsevier Clinical laboratory technicians Medical laboratory technicians medical technologists clinical laboratory technicians medical laboratory technicians
