       abstract = {Ce rapport d{\'{e}}crit la r{\'{e}}alisation d'une interface permettant {\`{a}} un op{\'{e}}rateur d'extraire de l'image d'un texte manuscrit des prototypes de caract{\`{e}}res et des les accumuler dans une base de donn{\'{e}}es devant servir ult{\'{e}}rieurement {\`{a}} la reconnaissance de l'{\'{e}}crit. L'utilit{\'{e}} d'une telle interface intervient dans le cas o{\`{u}} la reconnaissance de l'{\'{e}}crit s'applique {\`{a}} de longs documents ayant un style particulier (par ex. documents anciens). La m{\'{e}}thode utilis{\'{e}}e part d'une repr{\'{e}}sentation des caract{\`{e}}res par le contour et r{\'{e}}sout la difficult{\'{e}} que constitue l'isolement d'un caract{\`{e}}re en sur-segmentant l{\'{e}}g{\'{e}}rement l'image des contours par rapport {\`{a}} une segmentation en caract{\`{e}}res. L'op{\'{e}}rateur rassemble ensuite les segments pour former les prototypes de caract{\`{e}}re. This report describes the realisation of an interface by which an operator can extract character prototypes from the image of a handwritten text and accumulate them into a database, which will be used afterwards for text recognition. Such an interface is usefull in the case where text recognition is required for long documents with a particular writing style (e.g. ancient documents). The method applied in this system, based on a boundary representation of characters, solves in the following manner the difficulty of isolating a character. The boundary image is slightly over-segmented with respect to a segmentation into characters. The operator gathers then the segments composing a single character.},
