    A video-based text and equation editor for LaTeX
    (Pergamon Press, 2008-09) Öksüz, Ö.; Güdükbay, Uğur; Çetin, A. Enis
    In this paper we present a video based text and equation editor for LaTeX. The system recognizes what is written onto paper and generates the LaTeX code. Text and equations are written on a regular paper using a board marker, and a USB camera attached to a computer is used to capture and record the pen-tip positions in each consecutive image frame. Characters and symbols are represented as separate finite state machines (FSMs). They are written in an isolated manner and they are recognized on-line using the FSMs. In the last step, LaTeX code corresponding to recognized characters and symbols is generated. © 2007 Elsevier Ltd.
