Handwriting recognition can be differentiated into two categories i.e.online handwriting recognition and Offline handwriting recognition. I mainly focus on offline handwritingrecognition. It is also observed that majority of work for this language is for printed form rather thanhandwritten form. One can obtain very less OCR related research work for Gujarati script, especially forhandwritten form. I use Freeman chain code for feature extraction and then used Hidden Markov method.There is no benchmark dataset is available so it is generated by collecting sample from more than 100writers of different age group and gender. Keywords: Handwritten Recognition, Freeman Chain Code, Pre-processing, Classification I. INTRODUCTION The form of the text is varied from the scanneddocument to the typed text in various fonts. For humans,recognition of text is a trivial task, but to make amachine that recognizes characters is extremelydifficult. The current study is being focused onexploration of possible methods to develop an OCRsystem for Gujarati language when noise is present inthe signal. In order to understand the core challenges, athorough analysis of Gujarati Writing System has beendone. To know and understand the research in this field,existing OCR systems are studied. The Prominence wason finding workable segmentation technique anddiacritic handling for Gujarati words, and building arecognition module for these ligatures. To develop an OCR system Gujarati text, a completeprocedure is proposed as well as a testing application isalso made. Test results from this are reported andcompared with the previous work done in this area. II. METHODS AND MATERIAL A. Features of Gujarati Language Gujarati is regional language of state Gujarat in India. Gujarati is name of script which is written and spokenby people in Gujarat. Gujarati script has 34+2 constantsand 11 vowels. The structures of some Gujaratiharacters are very similar to Devnagri script. Devngari script has shirolekha on top of the characters, but Gujarati script has not. Gujarati script does not have the distinction of Lower and Upper Cases like English script. Gujarati script has combination of constants and vowels. Every vowel has a unique symbol, called vowels modifiers. Table 1 shows Gujarati vowels, consonants, matras, other symbols and some of the conjuncts [5]. Figure 1 : Gujarati Script[5]
