A ground-truthing tool for making a database of online handwritten mathematical expressions
نویسندگان
چکیده
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-truthed 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.

Transcript mapping for handwritten Chinese documents by integrating character recognition model and geometric context
Creating document image datasets with ground-truths of regions, text lines and characters is a prerequisite for document analysis research. However, ground-truthing large datasets is not only laborious and time consuming but also prone to errors due to the difficulty of character segmentation and the large variability of character shape, size and position. This paper describes an effective reco...

Handwritten digit recognition can be categorized as a classification problem. Probabilistic Neural Network (PNN) is one of the most effective and useful classifiers, which works based on Bayesian rule. In this paper, in order to recognize Persian (Farsi) handwritten digit recognition, a combination of intelligent clustering method and PNN has been utilized. Hoda database, which includes 80000 P...
متن کاملA hybrid classifier for handwritten mathematical expression recognition
In this paper we propose a hybrid symbol classifier within a global framework for online handwritten mathematical expression recognition. The proposed architecture aims at handling mathematical expression recognition as a simultaneous optimization of symbol segmentation, symbol recognition, and 2D structure recognition under the restriction of a mathematical expression grammar. To improve the c...
