  • Method and device for the binarization of pixel data
    Patent number: 5915037
    Abstract: The invention concerns a method and device for binarization of pixel data in which a number of black-and-white binary images each having binarization characteristics of different degrees of sensitivity is formed from a set of grey scale value binary data. A dimension S is calculated for each of these binary images, according to the equation ##EQU1## where FS designates the number of black binary pixels and U designates the number of black-and-white transitions. A selection of the binary image for which the dimension S is at its maximum is optimally carried out.
