Application of Rough Grid in Feature Extraction of Printed Tibetan Character
Wang Ru-shan · Science Technology and Engineering · 2009
A feature extraction approach for printed Tibetan character based on the improved rough grid is proposed in the paper.The extracted feature by using the new method can effectively decrease the influence that caused by the decline in the rate of recognition part due to the change of pixel's position in the image.The method can not only overcome high probability of misrecognition due to numerous Tibetan characters,but also by compared with the direction line element approach and non-modified rough grid,this method to extract feature also has the high recognition precision.
