In order to make writer identification a more consistent area of research, several authors have made efforts to build complete and concise forms in the sense that all letters and numerals would be captured. However, most of the works found in the literature are devoted to the English language, thus, they do not contemplate certain particularities of the Brazilian Portuguese language. This paper describes the Brazilian Forensic Letter database considering the image properties and important graphometric features such as, writing style, relative slant, relative relationship between letters and baseline, and relative placement habits. The database has 315 writers and we are continuing to collect data.
