Abstract :
An online graphics recognition system is presented, which provides users a natural, convenient, and efficient way to input rigid and regular shapes or graphic objects (e.g., triangles, rectangles, ellipses, straight line, arrowheads, etc.) by quickly drawing their sketchy shapes in single or multiple strokes. An input sketchy (hand-drawn) shape is immediately converted into the user-intended rigid shape based on the shape similarity and the time constraint of the sketchy line. Three different (rule-based, SVM-based, and ANN-based) approaches have been applied and compared in the system. Experiments and evaluation are also presented, which show good performance of the system
