Abstract

One of the major issues encountered in the recognition of handwritten mathematical expressions, is the non-linear nature of the symbols. The spatial positioning of each symbol with respect to the others implies mathematical relationships, but the ambiguous nature of handwriting can often lead to the misrecognition of these relationships. This paper describes the results of comparative testing of spatial analysis techniques that determine these relationships, in an effort to discover the most appropriate technique to be adopted during the development of an efficient recognition system.
