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.

Sener F.; Ikizler-Cinbis, N. (Academic Press Inc., 2015)Abstract In this work, we look into the problem of recognizing two-person interactions in videos. Our method integrates multiple visual features in a weakly supervised manner by utilizing an embedding-based multiple instance ...
şener, Fadime; Samet, Nermin; Duygulu, Pınar; Ikizler-Cinbis, N. (IEEE, 2013)In this work, we study the task of recognizing human actions from noisy videos and effects of noise to recognition performance and propose a possible solution. Datasets available in computer vision literature are relatively ...
Fractional Fourier transform pre-processing for neural networks and its application to object recognition Barshan, B.; Ayrulu, B. (Pergamon Press, 2002)This study investigates fractional Fourier transform pre-processing of input signals to neural networks. The fractional Fourier transform is a generalization of the ordinary Fourier transform with an order parameter a. ...
