Abstract :
This paper is concerned with the symbol segmentation and recognition task in the context of online sampled handwritten mathematical expressions, the first processing stage of an overall system for understanding arithmetic formulas. Within our system a statistical approach is used tolerating ambiguities within the decision stages and resolving them either automatically by additional knowledge acquired within the following processing stages or by interaction with the user. The recognition results obtained by different writers and expressions demonstrate the performance of our approach
