Abstract
A chemical reaction is represented on a paper by chemical expression which can contain chemical structures, symbols and chemical bonds. If handwritten chemical structures, symbols and chemical bonds can be automatically recognized from the image of Handwritten Chemical Expression (HCE) then it is possible to automatically recognize HCE. In this paper we have proposed an approach to automatically recognize benzene structure which is the most widely used chemical compound in aromatic chemical reactions. The proposed approach can recognize benzene structure from the image of HCE. We have developed two classifiers to classify the benzene structure from HCE. The first classifier is based on Support Vector Machine (SVM) and the second classifier is based on logistic regression. The comparative study of the both classification technique is also presented in this paper. The outcome of comparison shows that both classifiers have accuracy of more than 97%. The result analysis shows that classification technique based on SVM classification performs better than classification technique using logistic regression.
