The text presented hereinafter is describing the process of extraction of several characteristics required for recognition of Old Slavic Letters. The analysis is conducted over old Slavic scripts written with Cyrillic alphabet named “Constitutional Script”. It is a unique style of writing. The contour of the graphemes has been observed from several aspects: structural, graphic–aesthetical, geometrical and topological. As a result of such analysis, we have got semiotic style descriptions, harmonic proportions as well as characteristics of the letters that are used in the recognition process. The actual letter recognition is mainly founded on pixel recognition in particular segments like spots or blemishes, presence of vertical and horizontal lines as well as determination of compactness, complexity of the contour line and symmetry of the entire letter.
