Using a Geometric-Based Sketch Recognition Approach to Sketch Chinese Radicals

Paul Taele, Tracy Hammond

One approach to query a Chinese character involves referencing its subset called a radical, but sketching that character’s radical for querying is a function not supported by existing systems. Using the geometric-based LADDER sketching language and a Sezgin recognizer, we were able to construct an application which can first recognize handwritten sketches of Chinese radical, and then output candidate Chinese characters which contain that radical. Thus, we were able to demonstrate that a geometric-based sketch recognition approach can be used to easily build applications for recognizing symbols related to Chinese characters while working with few resources, requiring no training, and having reasonable recognition rates.
