Many E-documents in scientific and engineering disciplines contain mathematical expressions. Differential equations are commonly solved in pre-university and engineering studies along with many applications existing in the real world. Human beings perceive mathematical expressions as images and evaluate, which is one of the traits of human beings. The solutions range from simple to complex mathematical expressions. Automation of this trait of human beings is the dire need in the field of engineering education in the light of self directed study, a popular project of Govt. of India called SWAYAM. Proposed paper is an attempt to automate recognition of mathematical expressions from an image and consists of phases such as pre-processing, image segmentation, Loci feature extraction and text conversion. The text version is subjected to further evaluation. The proposed method gives an average accuracy of 96% conversion.

Abstract


Many E-documents in scientific and engineering disciplines contain mathematical expressions. Differential equations are commonly solved in pre-university and engineering studies along with many applications existing in the real world. Human beings perceive mathematical expressions as images and evaluate, which is one of the traits of human beings. The solutions range from simple to complex mathematical expressions. Automation of this trait of human beings is the dire need in the field of engineering education in the light of self directed study, a popular project of Govt. of India called SWAYAM. Proposed paper is an attempt to automate recognition of mathematical expressions from an image and consists of phases such as pre-processing, image segmentation, Loci feature extraction and text conversion. The text version is subjected to further evaluation. The proposed method gives an average accuracy of 96% conversion.
