INTRODUCTION Marathi, the OCR activities related to Gujarati language is Handwritten numeral Recognition becomes a prime area of very less. Shailesh A. Chaudhari and Ravi M. Gulati have research because of its potential, that can be used in various worked on separation and identification of mixed English – applications. Researchers have explored many Indian Gujarati printed numerals. Statistical approach is used as languages such as Hindi, Marathi, Telugu, Bangla, feature extraction with KNN classifier. An overall accuracy of Gurumukhi, Tamil and Kannada etc., but Gujarati is yet to be 99.23% is obtained with the same and an accuracy of 99.26% researched, explored and recognized to be on part with the for Gujarati and 99.20% for English numerals is obtained other Languages. This paper throws light on the Gujarati using KNN classifier [25]. Baheti M.J and Kale K.V have numeral recognition. Gujarati script is part of the Brahmic developed an algorithm to classify handwritten Gujarati family and it is similar to Devanagari script as most of the numerals using affine invariant moment feature extraction words are derived from Sanskrit. There is no header line at the technique. Authors have used various classifier to classify top of the letters or words in Gujarati script. Gujarati is the Gujarati numerals and highest accuracy of 92.28% is achieved mother tongue of the people of Gujarat state, one of the most using support vector machine. Accuracy of 90.04%,87.2% and spoken native languages and nearly 65 million people 84.1% is obtained using K-Nearest Neighbor, Gaussian converse in Gujarati. Gujarati numerals have various shapes distribution function and principal component analysis and many numerals have close resemblance which creates classifier [26].

  • The Origins, Evolution and Decline of the Khojki Script
    The origins, evolution and decline of the Khojki script Juan Bruce The origins, evolution and decline of the Khojki script Juan Bruce Dissertation submitted in partial fulfilment of the requirements for the Master of Arts in Typeface Design, University of Reading, 2015. 5 Abstract The Khojki script is an Indian script whose origins are in Sindh (now southern Pakistan), a region that has witnessed the conflict between Islam and Hinduism for more than 1,200 years. After the gradual occupation of the region by Muslims from the 8th century onwards, the region underwent significant cultural changes. This dissertation reviews the history of the script and the different uses that it took on among the Khoja people since Muslim missionaries began their activities in Sindh communities in the 14th century. It questions the origins of the Khojas and exposes the impact that their transition from a Hindu merchant caste to a broader Muslim community had on the development of the script. During this process of transformation, a rich and complex creed, known as Satpanth, resulted from the blend of these cultures. The study also considers the roots of the Khojki writing system, especially the modernization that the script went through in order to suit more sophisticated means of expression. As a result, through recording the religious Satpanth literature, Khojki evolved and left behind its mercantile features, insufficient for this purpose. Through comparative analysis of printed Khojki texts, this dissertation examines the use of the script in Bombay at the beginning of the 20th century in the shape of Khoja Ismaili literature.

Jain1, Harshal A. Arolkar2 Assistant Professor1, Associate Professor2 , GLS University Abstract: OCR termed as Optical Character Recognition, is a technique to convert mechanically or electronically an image, photo or scanned document of a handwritten or printed text into machine encoded text. HCR termed as Handwritten Character Recognition, is a form of OCR that is specifically designed to recognize the handwritten text. OCR and HCR nowadays are used extensively for information entry from printed or handwritten data records. In this paper we have done a survey on Gujarati Handwritten Character Recognition techniques. Keywords: OCR, Optical Character Recognition, HCR, Handwritten Character Recognition, Image Processing, Gujarati HCR, Gujarati Handwritten Character Recognition. I. INTRODUCTION Characters of any language are created using two types of mechanism namely; Digital and Handwritten Format. The digital characters are created with the help of a computer. The handwritten characters are the one’s that are written by person. Handwritten characters can further be classified into two categories: Offline and Online. The offline characters are written using any normal pen; while online characters are created using an optical pen or stylus on an electronic device.

Discovery number 1: A painting by Salvador Dali. It turns that clocks are not as bad as we think them to be. The units of time that segment the day into hours, minutes and seconds are in fact reconciled by the units of time that compose the Meso American Calendrical system or MAC for short. It was a surprise to me because one of the world’s foremost authorities in calendrical science the late Dr.Jose Arguelles had vilified the numbers of Western timekeeping as a most grievious error . So much so that he attributed much of the worlds problems to the use of the 12 month calendar and the 24 hour, 60 minute, 60 second day, also known by its handy acronym 12-60 time. I never bought into his argument that the use of those time factors was at fault for our largely miserable human-planetary condition. But I was content to dismiss mechanized time as nothing more than a convenient tool to facilitate the activities of complex societies.

    International Journal of Modern Trends in Engineering and Research www.ijmter.com e-ISSN No.:2349-9745, Date: 28-30 April, 2016 Comparison of Feature Extraction Techniques for Gujarati Isolated Numerals Dr. Mamta Baheti Department of Computer Science, Hislop College, Nagpur [email protected] Abstract— This paper is for recognition of isolated Gujarati numerals. As per the reported work, Gujarati is widely spoken across world along with Indian states. In the proposed study, we have used noisy handwritten numerals in procedure of training and testing. After applying pre-processing to the scanned image, they are then treated with the proposed algorithm. In our proposed algorithm we have used affine invariant moments and invariant moments as feature extraction technique and Gaussian distribution function as classifier. We produced pleasing results for some numerals. We compared the results for both the extraction techniques and found that for our database Affine invariant moments gave better results but they could be improved by giving better quality images for training and testing. Keywords- Affine Invariant Moments; Invariant Moments; Gaussian Distribution Function I. INTRODUCTION In the present scenario, every day task is being computerized. Each user wants the computer to have user-friendly interactions. In recent years a good amount of reported work has been contributed for recognition of handwritten characters. Variation in writing styles and recognition accuracy has a milestone to achieve. It has been noted that there are approximately 22 regional official languages are used in India [1-4]. Every regional official language has the wide variety as well some peculiar similarities. Out of these, one language is Gujarati which is spoken in Gujarat and some parts of India and also in South Africa.
