A Visual Approach to Sketched Symbol Recognition

Tom Y. Ouyang, Randall Davis
2009 International Joint Conference on Artificial Intelligence  
To address these challenges, we propose a new approach to sketched symbol recognition that focuses on the visual appearance of the symbols.  ...  We show that our method exceeds state-of-the-art performance on all three domains we evaluated, including handwritten digits, PowerPoint shapes, and electrical circuit symbols.  ...  This is important because letters and digits are often an essential part of sketched diagrams, where they may appear either as annotations (e.g., in electrical circuits) or as part of the underlying structure  ...
