- 論文の詳細を見る
This paper presents a tool for labeling online handwritten mathematical expressions with ground truth automatically. We apply symbol hypotheses for segmentation and spatial relationship for matching between a template expression and a sequence of input strokes. By using this tool, we experimentally made a ground-tmthed database contains 1,407 mathematical expressions and over 12000 symbols. Statistical features extracted from the ground-truthed database are to be used to determine spatial relationship in matching process.
