    Computer vision based text and equation editor for LATEX
    (IEEE, 2004-06) Öksüz, Özcan; Güdükbay, Uğur; Çetin, Enis
    In this paper, we present a computer vision based text and equation editor for LATEX. The user writes text and equations on paper and a camera attached to a computer records actions of the user. In particular, positions of the pen-tip in consecutive image frames are detected. Next, directional and positional information about characters are calculated using these positions. Then, this information is used for on-line character classification. After characters and symbols are found, corresponding LATEX code is generated.
