This paper aims at automatic recognition of onlinehandwritten mathematical expressions written on anelectronic tablet. The proposed technique involves twomajor stages: symbol recognition and structural analysis.A multiple-classifier consists of both parametric and non-parametricclassifier has been used for recognition ofsymbols. Parametric classifier is based on HiddenMarkov Model (HMM), whereas, non-parametricclassifier uses Nearest Neighbor classification scheme.Structural analysis uses several online and offlinefeatures to identify the spatial relationships amongsymbols. A context free grammar has been designed toconvert input expressions into their corresponding Latexstrings. Contextual information has been used to correctseveral errors occurring at both recognition andstructural analysis stage. A new method for evaluatingperformance of the proposed systems has beenformulated. Experiments on a dataset of considerable sizeshow high efficiency of the proposed system.
