International Journal of Scientific & Engineering Research Volume 2, Issue 10, Oct-2011 1 ISSN 2229-5518 Bilingual OCR System for Myanmar and English Scripts with Simultaneous Recognition Htwe Pa Pa Win, Phyo Thu Thu Khine, Khin Nwe Ni Tun Abstract - The increasing amount of development of the digital libraries worldwide raises many new challenges f or document image analysis research and development. Storing wide variety of document images in Digital library, for example, f or cultural, technical or historical, that are written in many languages, also create many advancement for present day digital image analysis systems. And when the Digital Library is concerned with Science and Technology documents, it needs to advance the OCR system to bilingual nature as most of them are written in Myanmar in combination with English letters. In this paper a bilingual OCR to simultaneously recognize the printed English and Myanmar texts is proposed including segmentation mechanism for the overlapping nature of Myanmar scripts. The effectiveness of the proposed mechanis m is proved with the experimental results of segmentation accuracy rates, comparisons of feature extraction methods and overall accuracy rates.

Then, one of the important tasks in machine learning is the electronic reading of documents. All various fields of the documents, magazines, reports and technical papers can be converted to electronic form using a high performance Optical Character Recognizer (OCR). And optical character recognition is a key enabling technology critical to creating indexed, digital library content, and it is especially valuable for scripts, for which there has been very little digital access 1, 2, 4. Furthermore, when the Digital Library is concerned with Science and Technology documents, it needs to advance the OCR system to bilingual nature as most of them are written in Myanmar in combination with English letters. Therefore, in this multilingual and multi-script world, OCR systems need to be capable of recognizing characters irrespective of the script in which they are written. In general, recognition of different script characters in a single OCR module is difficult. This is because features necessary for character recognition depend on the structural properties, style and nature of writing which generally differs from one script to another.
For example, features used for recognition of English alphabets are in general not good for recognizing Chinese logograms 3. Many OCR algorithms for English and other developed countries’ languages have been developed over the years for the paperless world and these can be available commercially ———————————————— Phyo Thu Thu Khine, University of Computer Studies, Yangon, Myanmar, Khin Nwe Ni Tun, University of Computer Studies, Yangon, Myanmar, or freely. But these systems can only recognize for specific single scripts and cannot do for Myanmar scripts. OCR system for Myanmar language is in little effort. In addition, there is no system that can recognize the documents that are written in Myanmar and English text. Therefore, a new system is proposed to recognize these documents simultaneously. 2 N ATURE OF M YANMAR S CRIPT Myanmar (Burmese) script is recognized as Tibeto/Burman language group, developed from the Mon script and descended from the Brahmi script of ancient South India.
It is the official language of Myanmar, where over 35 million people speak it as their first language. The direction of writing is from left to right in horizontally. In Myanmar script, there is no distinction between Upper Case and Lower Case characters. The character set consists of 35 consonants (including ‘ D’ and ‘ D’), 8 vowels signs, 7 independent vowels, 5 combining marks, 6 symbols and punctuations, and 10 digits. Each word can be formed by combining consonants, vowels and various signs. There are total of above 1881glyphs and has many similarity scripts in this language (e.g., D and D, D and D, and so on).
The shapes of Myanmar scripts are circular, consist of straight lines horizontally or vertically or slantways, and dots 11, 20. 3 R ELATED W ORK Many researchers have proposed several ways to implement various OCR systems 4, 5. The authors of 13-15 are discussed for the feature extraction methods. But in 7-9, they stated that the SVM classifier can be used as the effective recognizer. Some of the existing techniques used in OCR for Myanmar scripts are presented in 10, 11.
To the best of our knowledge, a comprehensive study on the success rate in terms of recognition accuracy for Myanmar printed text OCR system is yet to be reported.

These are scanned on a flatbed scanner at 300 dpi for digitization go for the preprocessing steps.
L INE D ETECTION AND SLICING To detect the lines, assume that the value of the element in the x th row and the y th column of the character matrix is given by a function f: 4.1 P REPROCESSING f ( x, y ) a xy (1) Preprocessing step is the basic crucial part of the OCR system. The recognition accuracy of OCR systems greatly depends on a Where, xy takes binary values (i.e., 0 for background white the quality of the input text image.
Firstly, we convert the raw pixels and 1 for black pixels). The horizontal histogram H h of input image into grayscale and then denoise it by removing noise using low pass Finite State Impulse Response (FIR) filter. The character matrix is calculated by the sum of black pixels in each row: Next, we binarize the clean image to a bi-level image by turning all pixels below some threshold to zero and all pixels about that threshold to one.

We find this threshold value using Otsu method. Finally, we deskew the binarized image with generalized Hough Transformed method. The detailed of the preprocessing steps are described in 21. H h ( x ) f ( x, y ) y And cut the lines depend on the H h ( x ) values. Character Segmentation (2) Similarly, the vertical histogram H v of the character matrix is calculated by the sum of black pixels in each column of the line segment: H v ( y ) f ( x, y ) x (3) Characters are segmented using these histogram values. However, this method alone is not enough for the Myanmar scripts. As for the small font, some character is not correctly segmented as shown in Fig.
System Design of the Myanmar OCR system 4.2 S EGMENTATION Segmentation is the process of the isolation of the individual character images from the refined image. It is considered as the main source of the recognition errors especially for small fonts. This is one of the most difficult pieces of the OCR system 4. We use the XY cut method on the use of histogram or a projection profile technique for segmentation. It has been proven as a classical and more accurate method in Devnagari scripts, for example, Bangla and Hindi and some of the South East Asia scripts, English and some Greek OCR 7, 10. The process of segmentation in our system mainly follows the following pattern: Line Detection and slicing Character Segmentation Figure 2.
Example of wrong segmentation error with projection And it may also be problem for some connected components. Moreover, the connected components cannot extract earlier as other languages because it can appear not only in shorter segments but also in longer segments that of the line height. That’s why the nature of Myanmar scripts cause over segmentation and under segmentation problems.
