Dotted and curved line character segmentation
SPIE Proceedings, 2011This paper presents new methodology for addressing curvature and segmentation in text as applied to dotted line images. Several improvements are provided, including methods and procedures for handling (a) curvature in text detection and segmentation, (b) rotation angle determinations, (c) isolation of only the character pixels in the image, (d) use ...

Character Segmentation Scheme for OCR System
International Journal of Computer Vision and Image Processing, 2011Automatic machine-printed Optical Characters or texts Recognizers (OCR) are highly desirable for a multitude of modern IT applications, including Digital Library software. However, the state of the art OCR systems cannot do for Myanmar scripts as the language poses many challenges for document understanding.

A survey on Arabic character segmentation
International Journal on Document Analysis and Recognition (IJDAR), 2012Arabic character segmentation is a necessary step in Arabic Optical Character Recognition (OCR). The cursive nature of Arabic script poses challenging problems in Arabic character recognition; however, incorrectly segmented characters will cause misclassifications of characters which in turn may lead to wrong results.

Machine printed character segmentation —; An overview
Pattern Recognition, 1995Abstract This paper is part I of a two-part review series. We present here an overview of the character segmentation techniques in machine-printed documents. So far, as to this point, in most Optical Character Recognition (OCR) systems, either commercial products or systems described in the published literature, recognition algorithms are developed ...

On the segmentation of touching characters
Proceedings of 2nd International Conference on Document Analysis and Recognition (ICDAR '93), 2002In many OCR systems, character segmentation is a necessary preprocessing step for character recognition. It is a critical step because incorrectly segmented characters are not likely to be correctly recognized. The most difficult cases in character segmentation are broken characters and touching characters. The problem of segmenting touching characters

A new robust character segmentation method
The 2014 2nd International Conference on Systems and Informatics (ICSAI 2014), 2014This paper proposed a robust segmentation method which can adopt varied conditions. The local binarization algorithm and global binarization are used as well as the blob analysis algorithm. Based on the long line fitting algorithm, the bottom frame connected with the characters is removed; based on the characters' gradient lines and average width and ...
