Image dataset to train a deep learning model to decode Leetspeak obfuscated characters

<p>The dataset contains an image database (18,981 images) that could be used to train a deep learning model to accurately detect characters. We have successfully used it to create a model that identifies characters encoded using LeetSpeak. The original dataset can be found in the Mondragon Unibertsitatea Repository -- https://gitlab.danz.eus/datasharing/ski4spam</p> <p>The training dataset consists of:</p> <p>- Alphabetic letters (a-z) written using different fonts and styles (regular, cursive, bold, cursive+bold)</p> <p>- Handwritten letters: English handwriting from the Chars74k dataset [2] which is available at http://www.ee.surrey.ac.uk/CVSSP/demos/chars74k/.</p>
