Novel Approach for Baseline Detection and Text Line Segmentation
Mahdi KeshavarzBahaghighat, Javad Mohammadi · International Journal of Computer Applications · 2012
Baseline detection and line segmentation are essential preprocessing steps of any OCR system.In this paper we have proposed a robust and fast method for base lines detection based on projected pattern analysis of Radon Transform.The algorithm have been tested on more than 350 samples including both printed and handwriting of Persian/Arabic, English and also multilingual documents.Obtained results indicate that in spite of narrow interline spaces and noisy components our method is capable to extract baseline in documents precisely.In addition, in the case of multi-frequencies pattern, it has been shown that proposed method can reach its performance to accurate detection of base lines.
