Handwritten Devanagari (Marathi) Compound Character Recognition using Seventh Central Moment

Compound character recognition of Devanagari Script (Marathi language) is one of the challenging tasks since the compound character is combination of one or more characters. These characters can be treated as fusion of two or more characters and hence these are complex in structure. Marathi, Hindi, Sanskrit and Nepali are written with Devanagari script. All these languages have compound characters. The characters may be formed with different sequence of combinations of basic characters such as vowels and consonants. Thus the recognition of compound characters makes this task more challenging to the researcher. So, as compared to English like Roman script, one of the major obstacles in handwritten Marathi character recognition is the large number of complex shaped compound characters. Considering the complexity of the problem, the present algorithm makes an attempt to identify the compound character. This paper discuss the recognition of compound character using combination of 7 Invariant Moment (Rotational Moment) and 7 order Central Moment(Translation Moment). SVM is used as classifier. The overall performance of the proposed system is 93.87%.
