An apparatus and method for detecting and analyzing imagery, wherein the apparatus includes an image data acquisition means, an image data conversion means, and an adaptive thresholding means. The image data acquisition means acquires image data from a document. The acquired image data is converted into a grayscale image frame by the image data conversion means. In addition, the adaptive thresholding means converts the grayscale image frame into a bi-tonal frame.

La présente invention concerne un dispositif et un procédé permettant une détection et une analyse d'imagerie, ledit dispositif comprenant un moyen d'acquisition de données d'image, un moyen de conversion de données d'image et un moyen de seuillage adaptatif. Le moyen d'acquisition de données d'image acquiert des données d'image d'un document. Les données d'image acquises sont converties en une trame d'image en échelle de gris par le moyen de conversion. En outre, le moyen de seuillage adaptatif convertit la trame d'image en échelle de gris en une trame bitonale.
