KHATT: Handwritten Arabic Text

<h3>Introduction</h3><br>
<p>KHATT: Handwritten Arabic Text was developed by <a href="http://www.kfupm.edu.sa/default.aspx">King Fahd University of Petroleum &amp; Minerals</a>, <a href="http://www.tu-dortmund.de/uni/International/index.html">Technical University of Dortmund</a> and <a href="https://www.tu-braunschweig.de/">Braunschweig University of Technology</a>. It is comprised of scanned Arabic handwriting from 1,000 distinct male and female writers representing diverse countries, age groups, handedness and education levels. Participants produced text on a topic of their choice in an unrestricted style. KHATT was designed to promote research in areas such as text recognition and writer identification.</p><br>
<h3>Data</h3><br>
<p>The majority of participants were natives of Saudi Arabia; the next largest group was from a collection of regional countries (Egypt, Jordan, Kuwait, Morocco, Palestine, Tunisia and Yemen). Most writers were between 16-25 years of age with high school or university qualifications.</p><br>
<p>Scanned text is presented as tiff images scanned at 200, 300 and 600 DPI (dots per inch). The source images are four-page tiffs consisting of metadata about the writer, fixed paragraphs and free writing. Image files of isolated paragraphs or lines are also included. Ground-truth files are presented as plain-text Unicode. Data is divided into training, validation and test sets.</p><br>
