    Automatyczna anotacja znaczników sztyftowych w procesie walcowania pielgrzymowego rur na zimno
    (Wydawnictwa AGH, 2010) Jabłoński, Mirosław; Pociecha, Daniel
    A system of automatic calculation of characteristic points in the process of tube cold rolling process has been presented. The very basic problem that has been addressed in this paper was a method of segmentation of particular regions in high resolution images i.e. reference board, tube area, and copper pin-markers. Three methods of adaptive thresholding have been examined for each type of object. Through application of computer vision algorithms duration of annotation phase has been greatly reduced in comparison to manual method.

    Zastosowanie algorytmów progowania adaptacyjnego do segmentacji barwnych obrazów mikroskopowych w badaniu metodą ELISPOT
    (Wydawnictwa AGH, 2008) Bieniecki, Wojciech; Węgrzyn, Michał; Grabowski, Szymon; Kościelska-Kasprzak, Katarzyna; Drulis-Fajdasz, Dominika; Mazanowska, Oktawia; Klinger, Marian
    An approach to segmentation of color microscope images, obtained in ELISPOT examination, which utilizes color components thresholding, is presented. Three methods of adaptive thresholding have been taken into account: Bernsen and two variants of Peaks & Valleys. Primarily, the algorithms were intended for monochrome images and the authors proposed their extension to RGB color space. The properties of the algorithms have been discussed basing on the tests carried out on images provided by the Wroclaw Medical Academy.
